g beats can be heard when Question 5 options: when sound waves interfere constructively when sound waves of same frequency interfere when sound waves of slightly different frequencies interfere when sound waves of different amplitudes interfere

Explanation:

Beats are produced when two sound waves from two  different sources having slightly different frequencies  interfere . Due to both constructive and destructive interference , high and low intensity sound is heard at some regular interval . This is called rate of beat formation . Amplitudes of sound may be same or different . High intensity sound heard per unit time is called beat . It is equal to difference of frequencies of the sound waves interfering

each other .

that would be because of both gravity and friction. so     c
