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

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.

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:

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.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

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

Light of frequency v is incident on a substance of threshold frequency v(v lt v) . The energy of the emitted photo-electron will be
