Derive Einstein's photoelectric equation. Explain the terms involved in it.
A photon of wavelength $3310 A^{\circ}$ falls on a photocathode and electron of energy $3 \times 1 0^{- 19}$ J is ejected . If the wavelength of the incident photon is changed to $5000 A^{\circ}$ . The energy of the ejected electron is $9.72 \times 1 0^{- 20} J$ . Calculate the value of Planck's constant and threshold wavelength of the photon.
