Question

Determine the wavelength of a radio wave that has a frequency of 9.90 x 10² Hz

Answer 1

`\lambda =3.83x10^5m`

Step-by-step explanation:

Hello!

In this case, since the relationship between the wavelength and frequency is given by considering the speed of light:

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

Thus, since the speed of light is about 3.0x10⁸ m/s and the frequency is 9.90 x 10² Hz or also 1/s, we compute the wavelength as follows:

`\lambda =(3.0x10^8m/s)/(9.90x10^2/s)\\\\\lambda =3.83x10^5m`

Best regards!
