Question

What is the frequency of radiation whose wavelength is 11.5 a0 ?

Answer 1

Answer:

The frequency of radiation is $2.61 \times 10^{17} s^{-1}$

Explanation:

Given:

Wavelength $\lambda = 11.5 \times 10^{-10}$ m

Speed of light $c = 3 \times 10^{8}$ $\frac{m}{s}$

For finding the frequency of radiation,

  $c = f \lambda$

  $f = \frac{c}{\lambda}$

  $f = \frac{3 \times 10^{8} }{11.5 \times 10^{-10} }$

  $f = 2.61 \times 10^{17}$ $s^{-1}$

Therefore, the frequency of radiation is $2.61 \times 10^{17} s^{-1}$
