Question

The wave equation represent by y=asin(At-Bx+C) A, B, C are constant. Dimension of A, B, C will be

Answer 1

As the dimension of trigonometric function is 1 i.e they are dimensionless.

Hence dimension of A is [T^-1]

[B]= [L^-1]

^{and C is an angle thus is dimensionless. As angle is ratio of two length s} 

^{Angle = length of Arc/ length of radius}
