JEE MAIN - Physics (2006 - No. 18)

The time taken by a photoelectron to come out after the photon strikes is approximately

$${10^{ - 4}}\,s$$

$${10^{ - 10}}\,s$$

$${10^{ - 16}}\,s$$

$${10^{ - 1}}\,s$$

Emission of photo-electron starts from the surface after incidence of photons in about $${10^{ - 10}}s.$$
