Kindly go through the solution

Since $\frac{f}{2} < f_{0}$

->current = 0

The work function of a metal is w₀and l is wavelength of incident radiation. There is no emission of photoelectron when

alok kumar singh

For no emission of electron

λ > λ₀

Q λ_{0 =}hc/w_0,so λ > hc/w₀

The work function of a metal is w0 and $λ$ is wavelength of incident radiation. There is no emission of photoelectron when

For no emission of electron

$λ > λ_{0}$

$? λ_{0} = \frac{h c}{w_{0}}, s o λ > \frac{h c}{w_{0}}$

Two stream of photons, possessing energies equal to twice and ten times the work function of metal are incident on the metal surface successively. The value of ratio of maximum velocities of the photoelectrons emitted in the two respective cases is x : y. The value of x is………

Case I :- $2 ? - ? = \frac{1}{2} m v_{1}^{2} . . . . . . . . (i)$

Case II :- $10 ? - ? = \frac{1}{2} m v_{2}^{2} . . . . . . . . (i i)$

$\Rightarrow \frac{1}{9} = \frac{v_{1}^{2}}{v_{2}^{2}}$

$\Rightarrow v_{1} : v_{2} = 1 : 3$

->x = 1
