Which of these statements is false ?

Options

A. photographic plate is sensitive for infrared rays
B. photographic plate is sensitive for ultraviolet rays.
C. infrared rays are invisible but make shadow like visible light
D. as compared to visible light photon, infrared photon have more energy.

Answer

D

Explanation

Here: velocity of electromagnetic waves in free space and wavelength
`v=3xx10^(8) m//s` , `lamda=150m`
Using the relation for the frequency of radio waves is given by
`=(v)/(lamda)=(3xx10^(8))/(150)`
`=2xx10^(6)Hz=2MHz`
