Question

Two waves are represented by the equations y₁ = asin (ωt +kx +0.57) m and y₂ = acos(ωt+kx) m where x is in meter and t in sec. The phase difference between them is

(a) 1.0 radian 

(b) 1.25 radian

(c) 1.57 radian

(d) 0.57 radian

Answer 1

Correct option (a) 1.0 radian 

Explanation:

=(1.57 -0.57) radian= 1 radian
