1 × 10^6 Hz what is the wavelength?

Answer in units of nm

1 × 10^6 Hz what is the wavelength?

Answer in units of nm

Expert's answer

Let's use the following formula:

L = c / f,

where c is the speed of the

light in vacuum and f is the frequency.

We get the following:

L = 3 * 10^8

/ 10^6 = 300 m = 3 * 10^11 nm.

L = c / f,

where c is the speed of the

light in vacuum and f is the frequency.

We get the following:

L = 3 * 10^8

/ 10^6 = 300 m = 3 * 10^11 nm.
