Frequently Asked Questions 

Question 1:What is the Doppler effect in the context of sound waves?

Answer: The Doppler effect is the change in frequency or wavelength of a wave as observed by an observer moving relative to the source of the wave. It is commonly experienced with sound waves, such as the change in pitch of a passing ambulance siren.

Question 2 :Explain the concept of superposition in wave interference.

Answer: Superposition is the principle that states when two or more waves meet at a point in space, the resultant displacement is the algebraic sum of the individual displacements of the waves.
