isn't the photon energy formula
E = hf = hc/λ
in the data and formula book?
you can do a quick elimination of some answers if you can remember that high frequency (short wavelength) photons carry more energy than low frequency (long wavelength) photons
A) hc/f would require energy to be lower for high frequency photons
D) hλ/c would require energy to be lower for short wavelength (high frequency) photons
