Answer:
ϕ (x,t) = 2πx/¶
Explanation:
According to mathematical representation of wave equation
y(x,t) = Asin (ωt-ϕ)
where ω is the angular velocity of the wave
ϕ is the phase angle
t is the time taken
ϕ depends on the horizontal displacement and wavelength of the wave. Therefore,
ϕ= kx... (1)
where k =2π/¶... (2)
Taking ¶ as the wavelength
Substituting equation 2 into 1
ϕ(x,t)= 2πx/¶
