A .  Infrared photon has more energy than the photon of visible light
B .  Photographic plates are sensitive to ultraviolet rays
C .  Photographic plates can be made sensitive to infrared rays
D .  Infrared rays are invisible but can cast shadows like visible light rays
Answer: Option A : A From the figure given below, you can clearly see that wave lengths of visible waves are lesser compared to wavelengths falling under infrared stage. Therefore, Infrared photon has less energy than the photon of visible light.
