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?
Final answer:
The original output light frequency of the material used in green lasers, before the frequency is doubled, is approximately 281,954,887,218,045 Hz.
Explanation:
The output light frequency of the material used before doubling can be determined using the wave equation, in which speed (c) equals wavelength (λ) times frequency (f): c = λf.
Given that the speed of light is a constant approximately equal to 300,000,000 meters per second, or 300,000,000,000,000,000 nanometers per second, and the wavelength is 532 nanometers after the frequency is doubled, we need to find the original frequency before doubling.
Considering the doubling, the original wavelength would be 2*532nm = 1064nm.
By substituting these values into the equation, we find, f = c/λ = 300,000,000,000,000,000 nanometers per second / 1064 nanometers = 281,954,887,218,045 Hz (approximately).

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 emit light at a deference wavelength, and the laser then uses a 'frequency double'. This doubles of the frequency emitted light, and the resultant light is the green 532 nm that we observe.
