Physics · Dual Nature of Radiation and Matter
In a photoelectric experiment, increasing the intensity of the incident light:
- 1increases the frequency of photons incident and the K.E. of the ejected electrons remains unchanged.
- 2increases the number of photons incident and the K.E. of the ejected electrons remains unchanged.✓
- 3increases the frequency of photons incident and increases the K.E. of the ejected electrons.
- 4increases the number of photons incident and also increases the K.E. of the ejected electrons.
Correct answer
increases the number of photons incident and the K.E. of the ejected electrons remains unchanged.
