Assertion (A): Ultraviolet radiations are scattered more as compared to the microwave radiations.
Reason (R): Wavelength of ultraviolet radiation is more than the wavelength of microwave radiation.
(a) Both A and R are true.
(b) A is true but R is false.
(c) A is false but R is true.
(d) Both A and R are false.
(b) A is true but R is false.
Explanation:
Scattering varies inversely as the fourth power of wavelength. Ultraviolet radiation has a much shorter wavelength than microwave radiation, so it is scattered more.
