Question

The mathematical expression for one dimensional wave travelling along the

positive x-direction is given as

y(x,t) = 0.02 sin(42 x - 1886t)m

where x is in meters and t is in seconds.
Determine the
1) direction of propagation of

the wave and calculate its
2) amplitude,
3) wavelength,
4) frequency and
5)velocity.​

Answer 1

Answer:

2) amplitude is 0.02 units

3) wavelength is 0.15 m

4) frequency is 300.16 Hz

5) velocity is 45.02 m/s
