Assertion (A) :Sunlight reaches us without dispersion in the form of white light and not as a
component.
Reason(R) : Dispersion takes place due to variation of refractive index for different wavelength
but in vaccum the speed of light is independent of wavelength and hence vaccum is a non- dispersive
medium
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true.
