Question

Find the frequency of wave if wavelength is 6cm?​

Answer 1

Answer:

How do you measure wavelength?

Use a photometer to measure the energy of a wave.

Convert the energy into joules (J).

Divide the energy by Planck's constant, 6.626 x 10-34, to get the frequency of the wave.

Divide the speed of light, ~300,000,000 m/s, by the frequency to get wavelength.

Answer 2

Explanation:

We know that frequency is c/wavelength

where c is the speed of light.

Hence, wavelength = 6cm = 0.06 m

and c = 3 * 10⁸ m/s

=> f = (3/0.06) * 10⁸

=> f = 5 * 10⁹ Hertz.
