Understanding the Relationship
* Wavelength (λ): Measured in meters (m) or nanometers (nm). It's the distance between two consecutive crests (or troughs) of a wave.
* Frequency (ν): Measured in Hertz (Hz). It's the number of waves that pass a fixed point in one second.
* Speed of light (c): A constant, approximately 3 x 10⁸ m/s in a vacuum.
The Equation
The relationship between wavelength, frequency, and the speed of light is:
c = νλ
Calculations
1. Convert wavelength to meters:
560 nm = 560 x 10⁻⁹ m
2. Rearrange the equation to solve for frequency:
ν = c / λ
3. Plug in the values:
ν = (3 x 10⁸ m/s) / (560 x 10⁻⁹ m)
4. Calculate the frequency:
ν ≈ 5.36 x 10¹⁴ Hz
Therefore, the frequency of 560 nm light is approximately 5.36 x 10¹⁴ Hz.
