At stopping potential, the photo electric current becomes

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

When a certain metal surface is illuminated wth light of frequency v, the stopping potential for photoelectric current is V_(0) . When the same surface is illumiinated by light of frequency (v)/(2) , the stopping potential is (V_(0))/(4) . The threshold frequency ofr photoelectric emissiohn id

When a certain metallic surface is illuminated with mono chromatic light of wavelength lambda , the stopping potential for photoelectric current is 3V_(0) . When the same surface is illuminated with light of wavelength 2lambda the stopping potential is V_(0) . The threshold wavelength for this surface for photoelectric effect is.

When a metallic surface is illuminated by a monochromatic light of lamda the stopping potential for photoelectric current is 4V_(0) when the same surface is illuminated by light of wavelength 3 lamda the stopping potential is V_(0) The threshold wavelength for this surface for photoelectric effect is -
