MCQ
Which of the following statements is not correct?
  • A
    Photographic plates are sensitive to infrared rays
  • B
    Photographic plates are sensitive to ultraviolet rays
  • C
    Infrared rays are invisible but can cast shadows like visible light
  • ✓
    Infrared photons have more energy than photons of visible light
✓

Answer

Correct option: D.
Infrared photons have more energy than photons of visible light
d
(d)

Infrared photons have less frequency than visible light. Hence, they have less energy.
