The Doppler effect describes frequency change when a source and observer are in relative motion. Sound pitches higher when approaching and lower when receding.
ସୂତ୍ର
f' = f × (v ± v_observer) / (v ∓ v_source)
ଷ୍ଟେପ୍-ଷ୍ଟେପ୍ ଗାଇଡ୍ |
- 1Enter source frequency and speed
- 2Enter observer and source velocities
- 3Apply Doppler formula with correct sign conventions
ସମାଧାନ ହୋଇଥିବା ଉଦାହରଣ
ଇନପୁଟ୍
f = 440 Hz, source approaching at 10 m/s, v = 340 m/s
ଫଳ
f' ≈ 454 Hz
Observed frequency increases
ଏଡ଼ାଇବା ଯୋଗ୍ୟ ସାଧାରଣ ଭୁଲ
- ✕Wrong sign conventions for approaching/receding
- ✕Using ground speed instead of relative speed
