Chapter 22, Problem 5P

To determine

The frequency of a microwave.

Answer to Problem 5P

The answer is $1.88\times {10}^{10}Hz$ .

Explanation of Solution

Given info:

Wavelength, $\lambda =1.60cm=0.016m$

Factor, $c=3.00\times {10}^{8}m/s$

Formula used:

The relation between frequency and wavelength: $f=\frac{c}{\lambda }$

Where,

  $f$ is frequency

  $\lambda$ is wavelength

  $c$ is a factor

Calculation:

Substitute the given values in formula, $f=\frac{c}{\lambda }$

  $f=\frac{3\times {10}^{8}m/s}{0.016m}=1.88\times {10}^{10}Hz$

Conclusion: The frequency is $1.88\times {10}^{10}Hz$ .
