Write the y-equation for a wave traveling in the negative x-direction with wavelength 50 cm, speed 4.0 m/s, and amplitude 5.0 cm
Zanzabum

Answer:

y = A sin(2\pi(\dfrac{x}{50})+ 8 t)

Explanation:

given,

wavelength, λ = 50 cm

speed, v = 4 m/s

Amplitude, A = 5 cm

general equation of the wave along x- axis

y = A sin(2\pi(\dfrac{x}{\lambda})\pm \nu t)

sign is positive when wave is traveling in negative direction

now,

\nu = \dfrac{v}{\lambda}

\nu = \dfrac{4}{0.5}

\nu = 8\ s^{-1}

inserting all the values

y = A sin(2\pi(\dfrac{x}{50})+ 8 t)

Hence, the y-equation of wave is equal to y = A sin(2\pi(\dfrac{x}{50})+ 8 t)
