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
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 photodsensitive material . What will be the photoelectric current if frequency is halved and intensity is doubled
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 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 .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.
Assertion : In photoelctric effect , on increasing the intensity of light , both the number of electrons emitted and kinetic energy of each of them get increased but photoelectric current remains unchanged. Reason : The photoelectric current depends only on wavelength of light .
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
