Wavelength Calculator

Find wavelength from wave speed and frequency.

Wave speed

Frequency (Hz)

Calculated Output

Wavelength 0.7795

Formula: λ = speed ÷ frequency

Step-by-Step Breakdown

1. Values used:

2. Wave speed = 343

3. Frequency = 440 Hz

5. Wavelength = Wave speed / Frequency = 343 / 440 = 0.7795

The math behind it

λ = wave speed ÷ frequency. Sound ≈ 343 m/s in air; light ≈ 3 × 10⁸ m/s.

440 Hz sound in air → 343 ÷ 440 = 0.78 m.

Higher frequency?

Shorter wavelength, for a fixed wave speed.
