frequency( and energy) of light is inversely proportional to wave length
frequency = c/λ
energy = hc/λ
so longer the wavelength ,lower will be energy and frequency
here light A has shorter wave length than light beam B.
Hence frequency (and energy) of A is higher than frequancy (and
energy)
of B
so only possible correct option is
answer
