Question 1

What is a Frequency and Wavelength?

Accepted Answer

Frequency (f) and wavelength (λ) are related by wave speed: v = fλ. For electromagnetic waves v = c = 3×10⁸ m/s. For sound in air at 20°C, v ≈ 343 m/s.

Question 2

How does the Frequency and Wavelength work?

Accepted Answer

λ = v / f Then: f = v / λ Then: EM waves in vacuum: c = 3×10⁸ m/s Then: Sound in air at 20°C: v ≈ 343 m/s.

Question 3

Can you give an example of how to use the Frequency and Wavelength?

Accepted Answer

Example: Input Middle C (262 Hz) sound wave gives a result of λ = 343/262 = 1.31 m.
