James Clerk Maxwell
The famous physicist James Clerk Maxwell was born on June 13, 1831, in Edinburgh, Scotland. He is considered as the scientist of the 19th century as he has laid the foundation for the important concepts of electromagnetic theory.
Light is an electromagnetic radiation whose wavelength can vary from visible to non-visible spectrum. The electromagnetic waves are of different types such as radio waves, microwaves; infrared, visible and ultraviolet light; X-rays, gamma rays etc.
James Clerk Maxwell Findings
Maxwell was the first scientist who bought all the established physics law of Gauss, Faraday, Ampere, and Fourth law. Maxwell studied Faraday’s work and demonstrated the speed of an electromagnetic wave travels at the speed of light. Maxwell incorporated laws of light, magnetism, and electricity into one theory which originated into electromagnetic theory.
Maxwell’s findings were published in 1873 ‘Treatise on Electricity and Magnetism’. He noted the propagation of light in electric and magnetic waves is perpendicular to each other. The electromagnetic theory has paved the wave for many technological innovations in the field of electricity. The electromagnetic waves are arranged as per the frequency and wavelength. The electromagnetic waves are propagated in the space in the form of sinusoidal waves.
Heinrich Hertz was the first person to utilize the principle of Maxwell to develop equipment for sending and receiving radio pulses. Based on James Clerk Maxwell theory today’s must-haves, television and microwave were created. Human life is not imaginable with electronic devices.
The James Clerk Maxwell is often compared with the famous scientist Sir Isaac Newton and Albert Einstein for his contributions of the fundamentals of nature.
He expired on November 5, 1879, Cambridge, Cambridgeshire, England.

Critical thinking: Electrical engineers should analyze their strengths and weaknesses and device procedures to solve problems. Critical thinking helps you in assessing the situation and get the best result out of it.
Functioning of circuits: The entire concept of electrical engineering is based on the circuits, as a student of electrical engineering, the staff makes sure that the student is well-trained about the functioning of are clear about the design and fixing of circuits.
Electrical Measurements: the flow of electrical current in the circuits and how the components of the circuit react to one another defines the functioning. Electrical measurements help in devising new electronic devices and also repair of the old electronic devices. The Candidates should be well-versed with the knowledge to read and manipulate the electrical instruments. The right quantity of electricity in the electronic device is required. Less electricity may not produce the desired effect and high may explode the device, an electrical engineer should be in a position to define the amount of electricity which can be flown in the circuit to allow easy and smooth functioning of the device.
Apart from the technical skills, the candidate should be a quick learner, have good interpersonal communication skills, Organizational Skills, and innovative thinking

How to learn Maths Easily
Often students assume subject Maths as one of the difficult subjects and are afraid to solve a maths problem. Maths is an inevitable subject which will be taught throughout the school and also in graduation, although the difficulty level may be different. In reality, Maths is an easy subject provided you learn all the formulas and apply little logic as per the question. Dedicate a defined time schedule for maths and make sure you stick to the timetable. Here we provide you the easy way to learn maths.
Practice Maths Problems
This very important aspect to master the subject, we have heard the proverb “practices makes the man perfect”. It is very apt for this subject and provides an easy way to learn maths. It is not a subject which students can learn by reading and listening. Try to solve as many problems as possible to master the subject.
Usually, student find it more easy to grab the subject in the calmness of night as there will be little or no disturbance.
Formula Booklet for Math Studies
Every chapter has a defined set of formulas and theorems, maintain a separate book to by-heart the formulas. Keeping a separate book will give you easy access to the formulas. You can also make a chart of the formulas and paste it on the wall, so you will remember the formula and have a glance it whenever you pass the place. Include concepts, terminology, and definitions also in the formula book which makes it handy to revise before working on the problems.
Study Environment
Select a place where you find it peaceful to study. Avoid noisy places and where there is constant interference of people, television or outdoor activities. This distracts attention and will not let you concentrate on the subject.
Understand the concept
As stated it is not a subject of reading, it requires a step-by-step process to solve complex solutions. Maths tricks help in solving the problem in a short time and also verification of the solution.
Identify & Clarify Doubts
Identify your weak areas, the step which takes a long time to solve, understand the concept. You can approach your teacher or friends and develop problem-solving skills.
Practical Application of Maths
Geometry and the probability concept can be applied in real life. This makes the subject interesting for the students.
CV Raman Brief Biography
Brief Biography of CV Raman
Sir Chandrasekhara Venkata Raman popularly known as Sir CV Raman was born at Tiruchirappalli in Southern India on November 7th, 1888 during the British period. His father was a lecturer and he acquired the skills of Maths and Physics from him. He graduated from Presidency College, Madras (Now Chennai) , in 1902. He studied B.A. and M. A. with the highest distinctions.
While traveling to Europe, CV Raman noticed the blue color of glaciers and the Mediterranean Sea. Curious Raman wanted to understand the reason and he carried out various experiments to understand the concept. He experimented on the scattering of light by water and ice. He utilized monochromatic light which was being emitted from a mercury lamp and allowed to fall on the transparent surface of water and ice. These recordings were made on a spectrograph. The lines which were obtained in the spectrum were referred to as ‘Raman Lines’ and the effect was called as ‘Raman effect’. CV Raman presented his theory in Bangalore on 16 March 1928 and won the Nobel Prize in Physics. Peter Pringsheim was able to successfully reproduce the effects and termed the coins ‘Raman Lines’ and as ‘Raman effect’. The great scientist breathed his last on 21 November 1970.
Raman spectroscopy:
This spectroscopic technique which relies upon inelastic scattering of photons. Monochromatic light that is visible (i.e. not ultra violet or infra red) or x-rays is used from a laser source to interact with molecular vibrations, phonons or other excitements in the system. The energy of laser photons shift up or down as a result. We are informed about the vibrational modes in the system due the shift in energy.
Raman spectroscopy is usually used to identify structural fingerprint of molecules.
The Scope and Excitement of Physics
CV Raman Achievements
- Sir CV Raman was awarded Nobel Prize for Physics for his work – Raman Scattering and Raman Effect in 1930.
- The government of India has honored CV Raman with Bharat Ratna the highest civilian award of India in 1954.
- His other prominent achievements include
- Fellow of the Royal Society in 1924 and knighted in 1929
- Franklin Medal in 1941
