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 meters and t is time in seconds This represents a wave

Options

A. travelling with a velocity of `30ms^(-1)` in the negative x direction
B. of wavelength pim
C. of frequency `30//pi` Hz
D. of amplitude `10^(-4)` m

Answer

A, B, C, D

Explanation

`y=10^(-4)sin 2pi((30t)/pi+x/pi)`
`y=10^(-4)sin 2pi (t/T+x/pi)`
