Question 155: Dual Nature of Matter and Radiation

Question

In a photoelectric experiment, increasing the intensity of incident light :

Accepted Answer

$$	o$$ Increasing intensity means number of incident photons are increased.
$$	o$$ Kinetic energy of ejected electrons depend on the frequency of incident photons, not the intensity.

Answer

increases the number of photons incident and also increases the K.E. of the ejected electrons

Answer

increases the frequency of photons incident and increases the K.E. of the ejected electrons

Answer

increases the frequency of photons incident and the K.E. of the ejected electrons remains unchanged

Answer

increases the number of photons incident and the K.E. of the ejected electrons remains unchanged
