Question

A certain radar installation transmits electromagnetic radiation with a wavelength of 3.5 cm. What is the frequency of this radiation?

Answer 1

Answer:

The frequency of the radiation = 10GHz

Step-by-step explanation:

The wavelength of the electromagnetic radiation, λ = 3.5 cm

λ = 3.5/100 m

λ = 0.035 m

The speed of light, c = 3 x 10⁸ m/s

Calculate the frequency (f) of the radiation using the formula:

`\begin{gathered} f=(c)/(\lambda) \\ \\ f=(3*10^8)/(0.035) \\ \\ f=10^(10)Hz \\ \\ f=10*10^9Hz \\ \\ f=10GHz \end{gathered}`

The frequency of the radiation = 10GHz
