Light of frequency 1.5 times the threshold frequency is incident on a photosensitive material.What will be the photoelectric current if the frequency is halved and intensity is doubled 1) Four times 2) One-fourth 3) Zero 4) Doubled

Light of frequency 1.5 times the threshold frequency is incident on a photodsensitive material . What will be the photoelectric current if frequency is halved and intensity is doubled

Light of frequency 1.5 times the threshold frequency is incident on a photosensitive material. If the frequency is halved and the intensity is doubled, the photoelectric current becomes

Light of frequency 1.5 times the threshold frequency is incident on a photo-sensitive material. If the frequency is halved and the intensity is doubled, the photoelectric current becomes

Radiation of frequency 1.5 times the threshold frequency is incident on a photosensitive material. If the frequency of incident radiation is halved and the intensity is doubled, the number of photoelectron ejected per second becomes:

Assertion: Light of frequency 1.5 times the threshold frequency is incident on photo-senstive material. If the frequency is halved and intensity is doubled, the photo current remains unchanged. Reason: The photo electric current varies directely with the intensity of light and frequncy of light.

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

Light of a particular frequency v is incident on a metal surface. When the intensity of incident radiation is increased, the photoelectric current

Light of frequency .25 v_0 is incident on a metal surface of threshold frequency 2 v_0 . If its frequency is halved and intensity is made three times then find the new value of photoelectric current.
