Learning Goal:To understand the standard formula for a sinusoidal traveling wave.One formula for a wave with a y displacement (e.g., of a string) traveling in the x direction isy(x,t)=Asin(kx−ωt).All the questions in this problem refer to this formula and to the wave it describes.1)What is the phase ϕ(x,t) of the wave?Express the phase in terms of one or more given variables ( A, k, x, t, and ω) and any needed constants like πϕ(x,t)=2)What is the wavelength λ of the wave?Express the wavelength in terms of one or more given variables ( A, k, x, t, and ω)...
