Question

Each question contains statement 1 and statement 2. Choose the correct answer (only one option is correct) from the following options.

Statement-1 : Photoelectric saturation current increases with the increases in frequency of incident light.
Statement-2 : Energy of incident photons increases with increases in frequency and as a result photoelectric current increases.

• A. Statement-1 is false, Statement -2 is true
• B. Statement -1 is true, Statement-2 is true; Statement -2 is a correct explanation for statement-1
• C. Statement -1 is true, Statement-2 is true; Statement -2 is not correct explanation for statement-1
• D. Both, Statement-1 and Statement -2 are false

Answer 1

Answer: (D)

Both, Statement-1 and Statement -2 are false

Both the statements are false
Photoelectronic saturation current is independent of frequency. It only depends on intensity of light.
It depends only on the no. of photons striking the surface of the metal per unit time.
The Kinetic energy of the knocked out electrons depends on frequency.
