A wave equation which gives the displacement along the Y direction is given by y = 10-4 sin(60t + 2x), where x and y are in metres and t is time in seconds. This represents a wave
(a) Traveling with a velocity of 30 m/s in the negative x direction
(b) Of wavelength x metre
(c) Of frequency 30/p hertz.
(d) All of the above
