Speed:
* Constant: The speed of light in a vacuum is a fundamental constant, denoted by "c", and is approximately 299,792,458 meters per second. It doesn't change regardless of the frequency or wavelength of the electromagnetic wave.
Wavelength:
* Independent: Wavelength is the distance between two successive crests (or troughs) of a wave. In a vacuum, the wavelength of an electromagnetic wave is determined by its frequency. It doesn't change independently.
Frequency:
* Independent: Frequency is the number of wave cycles passing a point per second. It's a property inherent to the source of the electromagnetic wave (e.g., the energy level transitions in an atom) and doesn't change in a vacuum.
The Relationship:
The key relationship is:
* c = fλ
Where:
* c is the speed of light in a vacuum
* f is the frequency of the wave
* λ is the wavelength of the wave
In summary:
* The speed of light in a vacuum is constant.
* Frequency is determined by the source and doesn't change in a vacuum.
* Wavelength is directly related to frequency through the speed of light. If the frequency remains constant, the wavelength also remains constant.
