Understanding the Relationship
* Speed of light (c): This is a constant, approximately 3.0 x 10⁸ meters per second (m/s) in a vacuum.
* Wavelength (λ): The distance between two consecutive crests or troughs of a wave.
* Frequency (f): The number of waves passing a point per second.
The relationship between these is:
c = λf
Solving for Frequency
1. Rearrange the equation: f = c / λ
2. Plug in the values: f = (3.0 x 10⁸ m/s) / (0.3 m)
3. Calculate: f = 1.0 x 10⁹ Hz (Hertz)
Important Note: The speed of an electromagnetic wave in a vacuum is always 3.0 x 10⁸ m/s. The frequency and wavelength are related, and changing one will affect the other.
