light is an electromagnetic wave

An electromagnetic wave is a disturbance, which does not require any material medium for its propagation and can travel even through vacuum. They are caused due to varying electric and magnetic fields. Radio waves and light waves are examples for ..

They do not require any medium for propagation; in other words, these waves can pass through vacuum They require medium for propagation i.e. these waves cannot pass through vacuum All electromagnetic waves travel with the same velocity Matter ..

Electromagnetic Nature of Light - In 1856, James Clark Maxwell proposed that light and other forms of radiant energy propagate themselves in the form of waves, through space. These waves have electric and magnetic fields associated with them and are..

In 1856, James Clark Maxwell proposed that light and other forms of radiant energy propagate themselves in the form of waves, through space. These waves have electric and magnetic fields associated with them and are called electromagnetic waves..

Waves carry energy from one place to another Transverse and longitudinal waves, Seismic waves Problems involving wavelength, frequency and wave speed Sound waves in a medium Radio waves, light and X-rays, electromagnet..

Depending upon their propagation in a medium, the waves are classified as follows: Mechanical waves or elastic waves and Electromagnetic waves..

Fig: 3.8 - Electromagnetic spectrum It is interesting to note that visible light, which the human eye detects, constitutes only a small portion of the total electromagnetic spectrum. The visible spectrum is shown separately. Violet colour has a radiation of minimum wav..

Electromagnetic theory of light was put forward by James Clerk Maxwell in 1873. According to this theory, light consists of fluctuating electric and magnetic fields propagating in the form of electromagnetic waves. But this theory failed to explain ..

In a homogeneous medium, the velocity of light waves is same everywhere. So the disturbances reach all such particles at the same time. These particles are at the same distance from the source and so they vibrate in phase with each other. The locus of all such particles is call..
