Two waves are represented by the equations Y1 = a sin(ωt- kx) and Y2

1.	Two waves are represented by the equations Y1 = a sin(ωt- kx) and Y2 = a cos (ω t – kx). What is the phase difference between them?
Answer» π/2 radians. Y₁ = a sin (ω t – kx). Y₂ = a cos (ω t – kx). = a sin(ω t – kx + π /2). ∴ Phase difference between Y₁ and Y₂is π/2 rad.

Answer»

π/2 radians.

Y₁ = a sin (ω t – kx).

Y₂ = a cos (ω t – kx).

= a sin(ω t – kx + π /2).

∴ Phase difference between Y₁ and Y₂is π/2 rad.
