Here's a breakdown:
* Wavelength (λ): The distance between two consecutive crests or troughs of a wave. It's measured in meters (m) or other units of length.
* Frequency (f): The number of wave cycles passing a fixed point per second. It's measured in Hertz (Hz).
The relationship:
The product of wavelength (λ) and frequency (f) is equal to the speed of the wave (v):
λ * f = v
This means:
* If the wavelength is shorter, the wave must oscillate more frequently to maintain the same speed.
* If the frequency is higher, the wavelength must be shorter to maintain the same speed.
Example:
Imagine a rope tied to a pole. If you shake the rope slowly, you'll create long waves with low frequency. If you shake it quickly, you'll create short waves with high frequency.
In the case of light:
* The speed of light (c) is constant.
* Therefore, a shorter wavelength of light means higher frequency and vice-versa. This explains why different colors of light have different frequencies:
* Red light has a longer wavelength and lower frequency.
* Blue light has a shorter wavelength and higher frequency.
In summary:
Wavelength and frequency are two fundamental properties of a wave that are inversely proportional to each other. Their relationship is governed by the speed of the wave.
