Frequency and Wavelength کا حساب کیسے لگائیں

Frequency and Wavelength کیا ہے؟

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.

فارمولا

f = c / λ | λ = c / f | where c = 3×10⁸ m/s (light) or speed of sound ≈ 343 m/s

f: Frequency (Hz)
λ: Wavelength (m)
c: Speed of wave (m/s)
