Question

According to Einstein's photoelectric equation, the plot of the kinetic energy of the emitted photoelectrons from a metal Vs the frequency of the incident radiation gives as straight the whose slope:

विकल्प

• depends both on the intensity of the radiation and the metal used

• depends on the intensity of the radiation

• depends on the nature of the metal used

• is the same for the all metals and independent of the intensity of the radiation

Answer 1

is the same for the all metals and independent of the intensity of the radiation

Explanation:

The slope of the graph of K.E and v is h, which is the same for all metals, according to Eqn. K.E = hv − Φ.
