The maximum kinetic energy of the photoelectrons is found to be

6.63 \times {10^{ - 19}}

J. When the metal is irradiated with a radiation of frequency

2 \times {10^{15}}

Hz, the threshold frequency of the metal is about

View answer and explanation

Correct option: B

1 \times {10^{15}}\mathrm{\;}{\mathrm{s}^{ - 1}}

Option B (

1 \times {10^{15}}\mathrm{\;}{\mathrm{s}^{ - 1}}

) is correct because it represents the threshold frequency calculated from the given maximum kinetic energy and frequency of the incident radiation.
