Formulas and Key Relations

1. Sound Waves and Basic Terms

v=f × λ

f=1/T

Speed of sound in air = 330 m/s

2. Reflection of Sound, Echo and Reverberation

t = 2d/v

d = vt/2

d = 340 × 0.1 / 2 ≈ 17 m

3. Speed of Sound in Air and Gas

v = √□

Speed of sound = total distance / total time = 2d/t

v = 1400 × t / 2

4. Uses of Echo and Applications

R = ct/2

Key relations

Wave velocity is given by v = f × λ, and frequency and time period are related by f = 1/T.
