Question

explain the wave equation for the progressive wave such is a Sin Omega T ​

Answer 1

progressive wave is defined as the onward transmission of the vibratory motion of a body in an ... Since, ω = 2π/T, the equation (3) can also be written as, ... y = a sin 2π 

Answer 2

Answer:

y=a sinπ(
