Question

The equation for a travelling wave is y = 4.6 Sin (3t-8x) Find: (a) Its frequency (b) Its wave length (c) Speed of the wave.​

Answer 1

Step-by-step explanation:

Step-by-step explanation:

Y = 5 Sin27(.2x-3t)

= 5 Sin(5.4x - 81 t)

Amplitude = 5 m

Angular frequency w = 81

frequency = w/ 2π = 81/(2 x 3.14)

-12.89

Wave length λ = 2π/ k,

k = 5.4

λ = 2π/ 5.4

= 1.163 m

Phase velocity=w / k

= 81/5.4

15 m/s.

The wave is travelling in + ve x - direction.
