How to Calculate the Frequency of Laser Light?

What is the red light wavelength emitted by a he-ne laser, and how can we find the frequency of the laser light? The red light emitted by a he-ne laser has a wavelength of 633 nm in air and travels at 3.00 x 10^8 m/s. To find the frequency of the laser light, we can use the relationship between velocity, frequency, and wavelength. Given: Wavelength (λ) = 633 nm = 633 x 10^-9 m Velocity (v) = 3.00 x 10^8 m/s We can use the formula: f = v / λ Substituting the values: f = (3 x 10^8) / (633 x 10^-9) f = 4.74 x 10^14 Hz Therefore, the frequency of the laser light is 4.74 x 10^14 Hz.

To calculate the frequency of laser light, we need to first determine the wavelength of the light and the velocity at which it travels. In this case, we are given that the red light emitted by a he-ne laser has a wavelength of 633 nm in air and travels at a velocity of 3.00 x 10^8 m/s.

By using the formula f = v / λ, where f is the frequency of the light, v is the velocity, and λ is the wavelength, we can plug in the values to find the frequency. In this case, we find that the frequency of the laser light is 4.74 x 10^14 Hz.

Understanding how to calculate the frequency of laser light can help us in various applications, such as telecommunications, spectroscopy, and laser technology. It allows us to determine the specific characteristics of laser light and how it behaves in different mediums.
