Solution

Phase Angle:
A wave that repeats as a function of time and position is referred to as a periodic wave. Amplitude, frequency, wavelength, speed, and energy describe the properties of the wave. The phase angle is used to describe the characteristics of a periodic wave.
Equation of wave is given by: $y (x, t) = A \sin (k x - ω t + ϕ) [y = v e r t i c a l p o s i t i o n, A = a m p l i t u d e, K = a n g u l a r w a v e n u m b e r, x = horizontal position of particle, ω = angular frequency, t = time, ϕ = initial phase]$
The phase angle refers to the angular component of a periodic wave.
in above equation $(k x - ω t + ϕ)$ represent phase angle.
