Which of the following is true as regards photo emission?
Velocity of emitted electrons is dependent on light intensity
Rate of photo emission is inversely proportional to light intensity
Maximum velocity of electron increases with decreasing wave length
Both holes and electrons are produced
Correct answer is C
As wavelength decreases, frequency increases and maximum velocity of electron increases.
