How are the wavelength and frequency of a sound wave related to its speed?
Wavelength, speed, and frequency are related in the following way:
Speed = Wavelength x Frequency
v = \( \lambda \nu\)
Explain how the human ear works.
Explain how defects in a metal block can be detected using ultrasound.
A sonar device on a submarine sends out a signal and receives an echo 5 s later. Calculate the speed of sound in water if the distance of the object from the submarine is 3625 m.
Explain the working and application of a sonar.
