Here’s a simple explanation of frequency and wavelength of an electromagnetic wave:
Frequency (f):
- It is the number of wave cycles (or vibrations) that pass a point every second.
- Measured in Hertz (Hz).
- Higher frequency means more waves pass per second.
Wavelength (λ):
- It is the distance between two consecutive peaks or troughs of the wave.
- Measured in meters (m).
- Longer wavelength means the waves are more spread out.
Relationship:
- Frequency and wavelength are inversely related.
- When frequency goes up, wavelength goes down, and vice versa.
- They are related by the formula:
Speed of light (c) = Frequency (f) × Wavelength (λ)
