Question

Which of the following is not true for the progressive wave
`ypi4sin2pi((t)/(0.02)-(x)/(100))`
where x and y are in cm and t in seconds.
A. The amplitude is 4 cm
B. The wavelength is 100 cm
C. The frequency is 50 Hz
D. The velocity of propagation is `2 cm//s`

Answer 1

Correct Answer - d
`V=(omega)/(k)=(100)/(0.02)=5000 cm//s`
