Please see attached for full problem.


Solution Preview

The electromagnetic waves (wave nature) or radiations (energy nature) are comprised of electric and magnetic field vectors vibrating perpendicular to each other in a plane normal to the direction of propagation of them. The frequency (f), speed (c) and wavelength (lambda) are related as,
c = f * lambda.

The speed of all the EM radiations be same in the free space, hence as frequecny increases, wavelegth decreases. On the basis of increasing wavelength or decreasing frequency the EM radiations ...
