Question

Why does the maximum kinetic energy of photoelectrons increase when frequency increases?

विकल्प

• Photon energy increases when frequency increases.

• Emission develops a measurable delay.

• The work function increases when frequency increases.

• The number of photons per second decreases.

Answer 1

Increasing frequency increases photon energy. Since \[K_{\max}=h\nu-\phi_0\], the maximum kinetic energy also increases.
