Question

Two waves of amplitude a1 and a2 respectively and equal frequency travel towards same point. The amplitude of the resultant wave is

Answer 1

Answer:

a1+a2 and a1-a2

Explanation:

if the two waves are in constructive phase then the resultant amplitude will be equal to a=a1+a2( maximum)

in destructive case a=a1-a2

resultant amplitude will be always between a1+a2and a1-a2

hope you this answer
