Stopping potential for photo electrons

Stopping potential for photo electrons

At the stopping potential, photoelectric current is "______________" .

When a certain metallic surface is illuminated with monochromatic light of wavelength lambda , the stopping potential for photo electric current is 6 v_(0) . When the same surface si illuminated with light of wavelength 2 lambda , the stopping potential is 2v_(0) . The threshold wavelength of this surface for photoelectric effect is -

When monochromatic light of wavelength lambda illuminates a metal surfrce, then stopping potential for photo electric current is 3V_(0) . If wavelength changes to 2lambda then stopping potential becomes V_(0) Threshold wavelength for photo electric emission is:

In condition of stopping potential value of photo-electric current will be……

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