A wave traveling in a string in the positive x direction has a wavelength of 35 cm, an amplitude of 8.4 cm, and a period of 1.2 s. What is the wave equation (in base SI units) that correctly describes this wave

Explanation:

It is given that,

Wavelength of a wave,

Amplitude,

Period of the wavelength, t = 1.2 s

The wave is traveling in a string in the positive x direction. We need to write the wave equation for this conditions.

The general equation of the wave when it is traveling in +x direction is given by :

A is amplitude

k is propagation constant

is angular frequency

So, the wave equation is given by :

Hence, this is the required solution.
