Frequency of photon having energy $66 eV$ is

A

$8 \times {10^{ - 15}}Hz$

B

$12 \times {10^{ - 15}}Hz$

C

$16 \times {10^{15}}Hz$

D

None of these

Solution

(c) $E = h\nu$

$\Rightarrow \nu = \frac{E}{h} = \frac{{66 \times 1.6 \times {{10}^{ – 19}}}}{{6.6 \times {{10}^{ – 34}}}}$

$ = 16 \times {10^{15}}Hz$
