Understanding the Relationship

* Speed of light (c): A constant value of approximately 3 x 10^8 m/s

* Wavelength (λ): The distance between two successive crests or troughs of a wave (given as 670 x 10^-9 m).

* Frequency (f): The number of waves that pass a point in one second.

The Formula

The relationship between these three is:

c = λ * f

Solving for Frequency

1. Rearrange the formula: f = c / λ

2. Substitute the values: f = (3 x 10^8 m/s) / (670 x 10^-9 m)

3. Calculate: f ≈ 4.48 x 10^14 Hz

Therefore, the frequency of a 670 nm light wave is approximately 4.48 x 10^14 Hz.
