Question

What is the wavelength, in metres, of a 28.27 GHz radar signal?

Answer 1

Wavelength of the radar signal is 0.0106 meters.

Step-by-step explanation:

It is given that,

Frequency of the radar signal,
`f=28.27\ GHz=28.27* 10^9\ Hz`

We need to find the wavelength of the radar signal. The relation between frequency and the wavelength is given by :

`\lambda=(c)/(f)`

c is the speed of light

`\lambda=(3* 10^8\ m/s)/(28.27* 10^9\ Hz)`

`\lambda=0.0106\ m`

So, the wavelength of the radar signal is 0.0106 meters. Hence, this is the required solution.

Answer 2

0.0106 m

Step-by-step explanation:

We have given that the frequency of the radar signal is
`f=28.27GHz=28.27* 10^9Hz`

Velocity of light
`c=3* 10^8m/sec`

We know that velocity = wavelength ×frequency

So
`3* 10^8=wavelength* 28.27* 10^9`

`wavelength=(3* 10^8)/(28.27* 10^9)=0.0106m`

So wavelength of the radar signal will be 0.0106 m
