Question

For a travelling harmonic wave `y=2.0 cos(10t-0.0080x+0.35)`, where x and y are in centimetres and t in seconds. What is the phase difference between oscillatory motion of two points separated by a distance of (a) 4m (b) 0.5 m (c ) `lambda//2` (d) `3lambda//4`

Answer 1

Correct Answer - (a) `6, 4 pi` rad , (b) `0.8 pi` rad
`pi` rad , (d) `(p//2)` rad
