PROPERTIES OF LIGHT

Let us recall the properties of light and the important aspects on refraction of light.

1.              Light is a form of energy.

2.              Light always travels along a straight line.

3.              Light does not need any medium for its propagation. It can even travel through vacuum.

4.              The speed of light in vacuum or air is, c = 3 × 108 ms–1.

5.              Since, light is in the form of waves, it is characterized by a wavelength (λ) and a frequency (ν), which are related by the following equation: c = ν λ (c - velocity of light).

6.              Different coloured light has different wavelength and frequency.

7.              Among the visible light, violet light has the lowest wavelength and red light has the highest wavelength.

8.              When light is incident on the interface between two media, it is partly reflected and partly refracted.
