MCQ
A photon will have less energy, if its:
  • A
    Wavelength is longer
  • B
    Wavelength is shorter
  • C
    Amplitude is less
  • D
    Data insufficient

Answer

  1. Wavelength is longer

Explanation:

$\text{E}=\frac{\text{hc}}{\lambda}$

$\text{E}\propto\frac{\text{1}}{\lambda}$

Hence, E is less if $\lambda$ is longer.
