Understanding the Relationship

The frequency (f) and wavelength (λ) of a wave are related by the following equation:

* f = c / λ

Where:

* f is the frequency (measured in Hertz, Hz)

* c is the speed of light (approximately 3.00 x 10⁸ m/s)

* λ is the wavelength (measured in meters, m)

Calculation

1. Substitute the values:

* f = (3.00 x 10⁸ m/s) / 3.55 m

2. Calculate the frequency:

* f ≈ 8.45 x 10⁷ Hz

Significant Figures

The wavelength (3.55 meters) has three significant figures. Our answer should also have three significant figures:

Answer: The frequency of the wave is approximately 8.45 x 10⁷ Hz.
