Question

The speed of light is a constant and approximately equal to 300,000,000 meters per second.

Green lasers emit light at a wavelength of 532 nm. However, the material that is used to make most green lasers does not emit light at 532 nm. Instead, it emits light at a different wavelength, and the laser then uses a “frequency doubler.” This doubles the frequency of the emitted light, and the resultant light is the green 532 nm that we observe.

1 meter is equal to 1,000,000,000 nanometers.

What is the output light frequency of the material used before doubling?

Answer 1

The material used before doubling will produce light at a frequency of 0.056 Hz.

What is the frequency?

The number of times a wave occurs repeatedly in a second is known as frequency.

The formula provides the frequency as,

$\rm v = \lambda \times f \\\\\ \rm f = \frac{v}{\lambda} \\\\ \rm f = \frac{3 \times 10^8}{532 \times 10^-9} \\\\ \rm f = 3 \times 10^{12} \\\\ f= 0.056 \ Hz$

Therefore, the material used before doubling will have an output light frequency of 0.056 Hz.
