Understanding the Relationship
The speed of light (c), frequency (f), and wavelength (λ) of an electromagnetic wave are related by the following equation:
c = fλ
Where:
* c = speed of light in a vacuum ≈ 3 x 10⁸ m/s
* f = frequency (in Hertz, Hz)
* λ = wavelength (in meters, m)
Solving for Frequency
1. Rearrange the equation to solve for frequency (f):
f = c / λ
2. Plug in the values:
f = (3 x 10⁸ m/s) / (7.6 x 10⁻⁶ m)
3. Calculate the result:
f ≈ 3.95 x 10¹³ Hz
Answer: The frequency of the electromagnetic wave is approximately 3.95 x 10¹³ Hz.
