Is Huygen's principle valid for longitudinal sound waves?

Define longitudinal wave.

What is longitudinal stationary waves ?

What are sound waves ?

State Huygens' Principle.

Define the following: Longitudinal waves

An earthquake generates both transverse (S) and longitudinal (P) sound waves in the earth. The speed of S waves is about 4.5 km//s and that of P waves is about 8.0 km/s. A seismograph records P and S waves from an earthquake. The first P wave arrives 4.0 min before the first S wave. The epicenter of the earthquake is located at distance about

What is superposition of sound waves ?

State Huygen's principle and hence explain the construction of spherical and plane wavefront.

Which of the following relation is correct for velocity of longitudinal waves?

The well known example of longitudinal wave is
