What Is Wavelength and Frequency?
Wavelength
Wavelength λ (lambda) refers to the distance between two successive crests or troughs of a wave. It is commonly measured in units such as meters, centimeters, or nanometers.
Frequency
Frequency (f ) is the number of wave cycles that pass a fixed point in one second. It is measured in hertz (Hz), where 1 Hz equals one cycle per second.
Wavelength to Frequency Relationship
Wavelength and frequency are inversely proportional and connected by the speed of the wave. The formula for their relationship is:
f = c / λ
Where:
- f = frequency (in Hz)
- λ= wavelength (in meters)
- c = speed of the wave (for light in a vacuum, c = 3 × 108 m/s)
For sound waves, the speed c depends on the medium, such as air, water, or steel.
How to Convert Wavelength to Frequency
To convert wavelength to frequency, follow these steps:
- Identify the wavelength in meters (λ).
- Determine the speed of the wave (c).
- Use the formula f = c / λ
Example 1: Converting Light Wavelength to Frequency
Problem: Find the frequency of light with a wavelength of 500 nm (nanometers).
Solution:
500nm = 500 × 10−9m
Using c = 3 × 108 m/s = 3 × 108 m/s:
f = 3 × 108 / 500 × 10−9 = 6 × 1014 Hz
Result: The frequency is 6×1014Hz.
