Vedclass · Answer

(B) According to Einstein's photoelectric equation,the maximum kinetic energy $K_{max}$ is given by $K_{max} = hv - hv_0$,where $h$ is Planck's constant,$v$ is the frequency of incident light,and $v_0$ is the threshold frequency.If the frequency $v$ is doubled to $2v$,the new kinetic energy $K'_{max} = h(2v) - hv_0 = 2hv - hv_0$. This is not equal to $2K_{max} = 2(hv - hv_0) = 2hv - 2hv_0$. Thus,the maximum kinetic energy does not double.Furthermore,the photocurrent depends on the number of photons incident per unit time,which is proportional to the intensity of the light,not the frequency. Therefore,Statement $1$ is false.Statement $2$ correctly states that $K_{max}$ depends linearly on frequency and photocurrent depends on intensity. Thus,Statement $2$ is true.
