Understanding the Relationship
* Frequency (f): How many wave cycles pass a point per second (measured in Hertz, Hz).
* Wavelength (λ): The distance between two consecutive crests or troughs of a wave (measured in meters, m).
* Speed of Light (c): The constant speed at which light travels in a vacuum (approximately 3 x 10⁸ m/s).
The Formula
The relationship between these three is:
c = fλ
Solving for Wavelength (λ)
1. Rearrange the formula: λ = c / f
2. Plug in the values:
* c = 3 x 10⁸ m/s
* f = 6.42 x 10⁻¹⁴ Hz
3. Calculate:
λ = (3 x 10⁸ m/s) / (6.42 x 10⁻¹⁴ Hz)
λ ≈ 4.67 x 10²¹ meters
Important Note: The wavelength you calculated is extremely long, far beyond the range of visible light. This frequency falls within the range of extremely low-energy electromagnetic radiation.
