At the stopping potential

(a) State three important properties of photons which describe the particle picture of electromagnetic radiation. (b) Use Einstein's photoelectric equation to define the terms (i) stopping potential and (ii) threshold frequency.

Define threshold frequency

When a certain photosensistive surface is illuminated with monochromatic light of frequency v, the stopping potential for the photo current is -V_(0)//2 . When the surface is illuminated by monochromatic light of frequency v//2 , the stopping potential is -V_(0) . The threshold frequency gor photoelectric emission is :
