An FM radio station broadcasts at 9. 23 × 107 Hz. Given that the radio waves travel at 3. 00 × 108 m/s, what is the wavelength of these waves? 0. 308 m 2. 77 m 3. 25 m 6. 50 m.

Respuesta :

The wavelength of these given radio waves is 0. 308 m. Option A is correct.

What is wavelength?

It is the distance between two consecutive crests or troughs. It can be calculated by the formula,

[tex]\lambda = \dfrac f s[/tex]

Where,

[tex]\lambda[/tex] - wavelength

[tex]f[/tex]- frequency = [tex]\bold {9. 23 x 10^7\ Hz}[/tex]

[tex]s[/tex] - speed =  [tex]\bold{3. 00 x 10^8 \ m/s}[/tex]

Put the values in the formula,

[tex]\lambda = \dfrac {\bold {9. 23 x 10^7\ Hz}}{\bold{3. 00 x 10^8 \ m/s}}\\\\\bold {\lambda = 0.308 \rm \ m}[/tex]

Therefore, the wavelength of these given radio waves is 0. 308 m.
