Chapter 16, Problem 6STP

To determine

To Choose: The correct option.

Answer to Problem 6STP

D. $7.43\times {\text{10}}^{14}\text{Hz}$

Explanation of Solution

Given:

The frequency of the light

Formula used:

  $\text{Frequency = }\frac{\text{Speed of light}}{\text{wavelength}}$

Calculation:

The speed of light is known as, $c=3\times {10}^8\text{}\text{m/s}$

Using given values in above, the frequency of the light will be,

  $\begin{array}{c}\text{Frequency = }\frac{\text{3}\times {\text{10}}^8}{\text{404}\times {\text{10}}^{-9}}\\ =7.43\times {\text{10}}^{14}\text{Hz}\end{array}$

Conclusion:

Hence, the frequency of the light is $7.43\times {\text{10}}^{14}\text{Hz}$ .
