11.Dual Nature of Radiation and matter
medium
$66 eV$ ની ઊર્જા ધરાવતા ફોટોનની આવૃત્તિ કેટલી થાય?
A
$8 \times {10^{ - 15}}Hz$
B
$12 \times {10^{ - 15}}Hz$
C
$16 \times {10^{15}}Hz$
D
એકપણ નહિ
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$
