What do transverse waves do?
They cause the motion of the medium perpendicular to their direction of propagation
What do longitudinal waves do?
They cause the motion of the medium in the direction of propagation
What is the wave function for any plane wave moving to the right along the x-axis with speed v?
What is a harmonic wave?
A wave that can be described by a sinusoidal function
This means it oscillates with a single, consistent frequency.
It follows the form of a sine or cosine function.
What is the general equation for a harmonic wave?
A= the amplitude,
k= the wave number,
ω= the angular frequency,
t= time,
x= position,
ϕ= the phase constant.
What is the formula for wavelength (λ) in terms of the wave number (k)?
What is the formula for wave speed (c) in terms of angular frequency (ω) and wave number (k)?
What happens as a wave moves along a string?
Energy is transferred from one segment of the string to the next.
What is power in the context of wave motion on a string?
Power is the rate of energy transfer.
It represents the rate at which work is done by the force exerted by one segment of the string on its neighbouring segment.
What is the formula for power transferred by the force on a string?
F=the tension force,
v= the transverse velocity.
