List of top Chemistry Questions on Photoelectric Effect asked in AP EAMCET

A light of frequency \( x \) Hz when falls on a metal plate emits electrons that have double the kinetic energy compared to when light of frequency \( y \) Hz falls on the same plate. The threshold frequency of the metal in Hz is:
If \( v_0 \) is the threshold frequency of a metal X, the correct relation between de Broglie wavelength \( \lambda \) associated with a photoelectron and frequency \( v \) of the incident radiation is:
