11.Dual Nature of Radiation and matter
easy

$100eV$ ऊर्जा के फोटॉन की आवृत्ति होगी $(h = 6.6 \times {10^{ - 34}}\,J{\rm{ - }}sec)$

A

$2.42 \times {10^{26}}Hz$

B

$2.42 \times {10^{16}}Hz$

C

$2.42 \times {10^{12}}Hz$

D

$2.42 \times {10^9}Hz$

Solution

$E = h\nu $

$\Rightarrow 100 \times 1.6 \times {10^{ – 19}} = 6.6 \times {10^{ – 34}} \times \nu $

$ \Rightarrow \nu = 2.42 \times {10^{16}}Hz$.
