Understanding the Relationship
* Speed of Light: Light travels at a constant speed (approximately 299,792,458 meters per second) in a vacuum, which we represent with the symbol 'c'.
* Wavelength: The distance between two consecutive crests or troughs of a wave is its wavelength (represented by the Greek letter 'λ').
* Frequency: The number of wave cycles passing a fixed point per second is its frequency (represented by the Greek letter 'ν').
The Formula
The relationship between these three is:
c = νλ
Solving for Frequency
1. Convert Wavelength to Meters:
* 520 mm = 520 x 10⁻⁶ meters (since 1 mm = 10⁻³ meters)
2. Plug the values into the formula:
* 299,792,458 m/s = ν * 520 x 10⁻⁶ m
3. Solve for frequency (ν):
* ν = 299,792,458 m/s / 520 x 10⁻⁶ m
* ν ≈ 5.76 x 10¹⁴ Hz (Hertz, which means cycles per second)
Therefore, the frequency of green light waves with a wavelength of 520 mm is approximately 5.76 x 10¹⁴ Hz.
