Question

four waves are expresses as
1.y1=a1sinwt
2.y2=a2sin2wt
3.y3=a3coswt
the interference is possible between ? ​

Answer 1

Answer:

Interference is possible in wave 1 and wave 3

Explanation:

When two waves of same frequency and constant phase difference moves along same direction superimpose at a point of medium then the resultant phenomenon is known as interference

Here we know

$y_1 = a_1 sin\omega t$

$y_2 = a_2 sin(2\omega)t$

$y_3 = a_3 cos(\omega t)$

now we can see that wave 1 and wave two have different frequency so these two waves will not show interference

While wave 1 and wave 3 will show interference as they have same frequency and constant phase difference.
