Answer to Question #82716 in Physics for Aish

Question

Y= 10^3cos( 1/50x - 1/2500t + π/3 )
Find initial phase , final phase and maximum amplitude.

Answer 1

The general equation of the harmonic wave

y(x,t)=A cos⁡〖(ωt-kx+φ_0)〗

The initial phase

φ_0=π/3

The phase

φ=1/50 x-1/2500 t +π/3

The amplitude

A=〖10〗^3

Answers:π/3,1/50 x-1/2500 t +π/3,〖10〗^3
