Blue light can eject electrons from a Photo-sensitive surface, while orange cannot. Will violet and red light eject electrons from the same surface?

Text Solution

Verified by Experts

`E = hv = (hc)/(lambda)`
As wavelength of red light is more than that of orange light, so red light can not eject electrons from metal surface.
As wavelength of violet light is less than wavelength of blue light, so violet light can eject electrons from the metal surface.

The question given below consist of an assertion (A) and a reason ( R). Use the following key to choose the appropriate answer to these questions from the codes (a), (b), ( c) and (d) given below: (a) Both A and R are true and R is the correct explanation of A. (b) Both A and R are true but R is NOT the correct explanation of A. (c) A is true but R is false. (d) A is false and R is also false. Assertion: Kinetic energy of photo electrons emitted by a photosensitive surface depends upon the intensity of incident photon. Reason: The ejection of electrons from metallic surface is possible with frequency of incident photon below the threshold frequency.
