Choose the incorrect statement:A. The velocity of photoelectrons is directely proportional to the square root of wavelength of lightB. The number of photoelectrons emitted depeds upon the intensity of incident lightC. The velocity of photoelectron is directely proportional to the frequency of the incident lightD. The velocity of the photoelectrons is inversely proportional to square root of the frequency of the light. |

Answer» Correct Answer - a,c,d As `K=hv-phi_(0)` or `1/2mv^(2)=(hc)/lambda-phi_(0)` `:. v prop sqrt(v)` or `v prop1/(sqrt(lambda))` so option `a,c,d` are incorrect as no. of photoelectrons depends on intensity of incident light, so, option b is correct. |
