When monochromatic light falls on a photosensitive material, the number of photoelectrons emitted per second is n and their maximum kinetic energy is `K_(max)`. If the intensity of the incident light is doubled keeping the frequency same, then:

A

Both n and `K_(max)` are doubled

B

Both n and `K_(max)` are halved

C

n is doubled but `K_(max)` remains the same

D

`K_(max)` is doubled but n remains the same

The frequency of incident light falling on a photosensitive metal plate is doubled, the KE of the emitted photoelectrons is

The photoelectros emitted by an illuminted surface have a maximum kinetic energy of 3.0 eV. If the intensity of the light is tripled, What is the maximum kinetic energy of photoelectrons now?

The maximu kinetic energy (E_(k)) of the photoelectron varies with frequency (v) of the incident light as shown by the curve:

Assertion: A photosensitive surface is illuminated by a monochromatic light of wavelength lambda and intensity I. The number of photoelectrons emitted per second is doubled when the intensity of light is doubled. However, the maximum speed of emitted electrons remains unchanged. Reason: The number of electrons emitted per second is directly proportional to the intensity of the incident light. The kinetic energy of the emitted photoelectrons is independent of the intensity of the light.

When monochromatic radiation of intensity I falls on a metal surface, the number of photoelectrons and their maximum kinetic are N and T respectively. If the intensity of radiation is 2 I, the number of emitted electrons and their maximum kinetic energy are respectively.

Assertion : Photoelectric current depends on the intensity of incident light. Reason : Number of photoelectrons emitted per second is directly proportional to intensity of incident radiation.

When monochromatic light of wavelength 620 nm is used to illuminate a metallic surface, the maximum kinetic energy of photoelectrons emitted is 1 eV. Find the maximum kinetic energy of photoelectron emitted (in eV) if a wavelength of 155 nm is used on the same metallic surface. (hc = 1240 eV-nm)
