Answer:
Asin[2πf(t+z/v)]
Asin[2πf(t−z/v)]
Step-by-step explanation:
A represent the amplitude of the wave
The mathematical representation of a wave is given as Asin(wt + Ѳ)
Ѳ= wt1
Asin (wt + wt1 )
t1= x/ v
x represent the distance
v represent the velocity
t1 represent the time taken by the wave.
The sign is positive if moving from the left to the right
The sign is negative if moving from the right to the left
