What is the relationship between wavelength and frequency of light in physics?

Calculating the Frequency of Light from Wavelength

Have you ever wondered how we can determine the frequency of light based on its wavelength? Let's dive into the exciting world of Physics to find out!

When it comes to understanding the frequency of light, we need to grasp the relationship it shares with the wavelength. In Physics, there's a fundamental formula that connects these two properties, which is c = fλ.

The speed of light (c) is a constant value, approximately 3.00 x 10^8 meters per second in vacuum. By rearranging this formula, we can solve for the frequency (f) in terms of wavelength (λ).

For our specific case of a helium laser emitting light with a wavelength of 633 nm (or 633 x 10^-9 meters), we can plug in the numbers and calculate the frequency:

f = c / λ

f = (3 x 10^8 m/s) / (633 x 10^-9 m)

After performing the calculation, we arrive at a frequency of approximately 4.74 x 10^14 Hz for the light emitted by the helium laser.
