Question

y=60cos(1800t-6x) represents a wave then find the wavelength​

Answer 1

Explanation:

=60cos(1800t−6x),y is in microns.

y=60cos(1800t−6x)×10−6

v=dtdy = particle velocity=60×10−6×1800sin(1800t−6x)

vparticle, max=6×18×10−3

vwave=kω;ω=1800;K=6

vwave=61800=300

vwavevparticle. max=3006×18×10−3=36×10−5=3.6×10−4
