Question

1. Light of wavelength 900x10-9 m is emitted by a source. What is its frequency?​

Answer 1

therefore the frequency = 6×10^14

Answer 2

The frequency of the light is "$6\times 10^{14}$".

Given values:

Wavelength,

$\lambda = 900\times 10^{-9} \ m$

As we know the formula,

→ $Frequency = \frac{C}{\lambda}$

By substituting the values, we get

→                   $= \frac{3\times 10^8}{900\times 10^{-9}}$

→                   $= \frac{10^8}{300\times 10^{-9}}$

→                   $= 6\times 10^{14}$

Thus the above response is correct.
