Answer 1

✓ velocity= wavelength* frequency

✓ velocity= frequency* wavelength

✓ velocity= (1/time)* wavelength for

✓ Echo:2* distance/time= speed of sound

Answer 2

Answer.

Velocity = Wavelenght × Frequency Velocity = Frequency × Wavelengh Velocity = (1/Time) × Wavelengh For Echo: 2 × Distance / Time = Speed of sound
