Question

20. GP A sinusoidal wave traveling in the negative x direction (to the left) has an amplitude of 20.0cm, a wavelength of 35.0cm, and a frequency of 12.0Hz. The transverse position of an element of the medium at t=0, x=0 is y= 3.00 cm, and the element has a positive velocity here. We wish to find an expression for the wave function describing this wave. the wave Find (d) the angular frequency omega and

Answer 1

The angular frequency of the wave is determined as 75.4 rad/s.

What is wave function?

A wave function is a mathematical equation for the motion of the wave.

y(x, t) = A sin(kx + ωt + Φ)

where;

• ω is angular speed
• k is angular wavenumber
• Φ is phase angle

What is angular frequency?

The angular frequency is the angular displacement of any wave element per unit of time or the rate of change of the waveform phase.

Angular frequency

ω = 2πf

ω = 2π(12)

ω = 75.4 rad/s

Thus, the angular frequency of the wave is determined as 75.4 rad/s.
