Question

A plane progressive wave is represented by the equation y =2sin (2000πt- 0.5x) the symbols have their usual meanings. What is the frequency of the wave and the wavelength

Answer 1

Step-by-step explanation:

As w = 2000π

2πf= 2000π

f= 1000Hz

speed = wavelength × f= w/k

wavelength = 2000π/ (0.5× 1000)

= 4π

or

12.57
