Question

A transverse wave travelling on a stretched string is is represented by the equation
`y =(2)/((2x - 6.2t)^(2)) + 20`. Then ,
A. velocity of the wave is `3.1m//s`
B. amplitude of the wave is `0.1m`
C. frequency of the wave is `20 Hz`
D. wavelength of the wave is `1m`

Answer 1

Correct Answer - A::B
`:. v = ("Coefficient of t")/("Coefficient of x")`
`= (6.2)/(2)= 3.1 m//s`
`A = (2)/(20) = 0.1 m`
