Question

What is the frequency of a microwave that has a wavelength of 0.050 m?

Answer 1

Answer:

$6x10^9Hz$

Explanation:

we use a formula that relates the frequency and the wavelength:

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

where $f$ is the frequency of the wave, $c$ is the speed of light $c=3x10^8m/s$, and $\lambda$ is the wavelength.

We know that the wavelength is: $\lambda=0.050m$, so substituting the known values in the equation for the frequency we get:

$f=\frac{3x10^8m/s}{0.05m} \\f=6x10^9s^{-1}=6x10^9Hz$

The frequency is:

$6x10^9Hz$

Answer 2

Frequency    Wavelength 1/4 Wavelength 1/20 Wavelength 1/100 Wavelength
600 MHz          0.5 meters         12.5 cm               2.5 cm                       5.0 mm

if that helps at all
