AIEEE 2004 | Dual Nature of Radiation Question 169 | Physics

According to Einstein's photoelectric equation, the plot of the kinetic energy of the emitted photo electrons from a metal $$Vs$$ the frequency, of the incident radiation gives as straight the whose slope

depends both on the intensity of the radiation and the metal used

depends on the intensity of the radiation

depends on the nature of the metal used

is the same for the all metals and independent of the intensity of the radiation

Two identical photo-cathodes receive light of frequencies $${f_1}$$ and $${f_2}$$. If the velocities of the photo electrons (of mass $$m$$ ) coming out are respectively $${v_1}$$ and $${v_2},$$ then

$$v_1^2 - v_2^2 = {{2h} \over m}\left( {{f_1} - {f_2}} \right)$$

$${v_1} + {v_2} = {\left[ {{{2h} \over m}\left( {{f_1} + {f_2}} \right)} \right]^{1/2}}$$

$$v_1^2 + v_2^2 = {{2h} \over m}\left( {{f_1} + {f_2}} \right)$$

$${v_1} - {v_2} = {\left[ {{{2h} \over m}\left( {{f_1} - {f_2}} \right)} \right]^{1/2}}$$
