Jinsi ya kukokotoa Doppler Effect

Doppler Effect ni nini?

The Doppler effect describes frequency change when a source and observer are in relative motion. Sound pitches higher when approaching and lower when receding.

Fomula

f' = f × (v ± v_observer) / (v ∓ v_source)

Mwongozo wa Hatua kwa Hatua

1Enter source frequency and speed
2Enter observer and source velocities
3Apply Doppler formula with correct sign conventions

Mifano Iliyotatuliwa

Ingizo

f = 440 Hz, source approaching at 10 m/s, v = 340 m/s

Matokeo

f' ≈ 454 Hz

Observed frequency increases

Makosa ya Kawaida ya Kuepuka

✕Wrong sign conventions for approaching/receding
✕Using ground speed instead of relative speed
