(i) List any five properties of light
(ii) State Rayleigh' law of scattering.

Explanation

(a) Light is a from of energy .
(b) Light always travel along a straight line.
(c) Light does not need any medium for its propagation . It can even travel through vacuum.
(d) The seed of light in vacuum or air is `C =3 xx10^(8)"ms"^(-)`
(e) Different coloured light has different wavelength and frequency.
(ii) Rayleigh.s scattering law sates that .. The amount of scattering of light is inversely proportional to the fourth power of its wavelength.. .
Amount of scattering `S prop 1/lamda^4`
