1.	The displacement of the wave given by equation `y(x, t)=a sin (kx - omega t +phi), ` where`phi=0` at point x and t = 0 is same as that at pointA. `x+2npi`B. `x+(2npi)/k`C. `kx + 2npi`D. Both (a) and (b)
Answer» Correct Answer - b `y(x,0)=a sin kx = asin (kx+2npi)` `=a sin k (x+ (2npi)/k)` `rArr` The displacement at points x and `(x+ (2npi)/k)` are the same, where `n= 1, 2, 3,…`
