Question

Calculate the wavelength of a microwave
of frequency 8.0 GHz.​

Answer 1

Explanation:

wavelength = speed of light/frequency

= 3*10^8/(8*10^9)

= 3/8 *10-1 = 0.0375 m

Answer 2

The wavelength of microwave is 0.0375 meters.

Explanation:

Given that,

Frequency of the microwave, $f=8\ GHz=8\times 10^9\ Hz$

To find,

The wavelength of the microwave

Solution,

We know that microwave is a type of electromagnetic wave. It travels with the speed of light. If $\lambda$ is its wavelength. So,

$c=f\lambda$

$\lambda=\dfrac{c}{f}$

$\lambda=\dfrac{3\times 10^8\ m/s}{8\times 10^9\ Hz}$

$\lambda=0.0375\ m$

So, the wavelength of microwave is 0.0375 meters. Hence, this is the required solution.
