MCQ
A photon will have less energy, if its:
- ✓Wavelength is longer
- BWavelength is shorter
- CAmplitude is less
- DData insufficient
✓
Answer
Correct option: A.
Wavelength is longer
$\text{E}=\frac{\text{hc}}{\lambda}$
$\text{E}\propto\frac{\text{1}}{\lambda}$
Hence, $E$ is less if $\lambda$ is longer.
