You are looking for AIEEE Physics question paper so here are some questions of Physics question paper: Statement-1 : When ultraviolet light is incident on a photocell, its stopping potential is V0 and the maximum kinetic energy of the photoelectrons is Kmax. When the ultraviolet light is replaced by Xrays, both V0 and Kmax increase. Statement-2 : Photoelectrons are emitted with speeds ranging from zero to a maximum value because of the range of frequencies present in the incident light. (1) Statement-1 is true, Statement-2 is true; Statement-2 is the correct explanation of Statement-1. (2) Statement-1 is true, Statement-2 is true; Statement-2 is not the correct explanation of Statement- 1. (3) Statement-1 is false, Statement-2 is true. (4) Statement-1 is true, Statement-2 is false. 34. 4 Sol. Since the frequency of ultraviolet light is less than the frequency of X–rays, the energy of each incident photon will be more for X–rays K.E photoelectron = hn - j Stopping potential is to stop the fastest photoelectron 0 h V e e n j = - so, K.Emax and V0 both increases. But K.E ranges from zero to K.Emax because of loss of energy due to subsequent collisions before getting ejected and not due to range of frequencies in the incident light.       For compete question paper kindly download question paper in pdf file and it is free for you.
