Question

Which equation was used by Albert Einstein to explain the photoelectric effect? [E = energy, h = Planck’s constant, and v = frequency.] E = h/v E = hv E = v/h E = h - v

Answer 1

Answer:

E = hv

Explanation:

• The photoelectric effect is a phenomenon when the electromagnetic waves of a particular wavelength strike on the metal plate like zinc, it ejects the free electrons.
• The ejected electrons have the kinetic energy and this energy is responsible for the electric energy.
• The kinetic energy of the emitted electrons is linked with the frequency of the incident rays.
• If the rays hitting the metal plate is below the minimum required threshold value, the photoelectrons are not ejected.
• The photoelectric equation is given by

                            E = hν - ∅

Where, ∅ is the minimum energy required to remove an electron.
