Wave Motion

A wave motion is defined as the propagation of disturbances or transfer of energy and momentum from the state of rest or equilibrium to another point in a medium without any actual transfer of matter between them. In a simple explanation, it is the propagation of energy through a medium that is produced due to the repeated vibrations of the particles. Common things we see day to day like waves on water oscillation of a pendulum or bell, light wave, and all the subatomic particles exhibiting wavelike properties. The propagation of waves depends on the medium and their properties. The wave function is the disturbance that produces waves as a function of time. This disturbance oscillates periodically with a fixed frequency and wavelength. There are linear wave motion and non-linear wave motion based on their propagation, motion, and time period where linear wave motion is like sinusoidal waves and non-linear wave motion like a wave motion that gets interrupted in the middle of their propagation.

Two identical point sources are generating waves with the same frequency and amplitude. The two sources are in phase with each other, so the two sources generate wave crests at the same instant. The wavelength of the waves is equal to the distance between the two sources. A. List all the labeled points where the waves from the two sources constructively interfere. If there are no such points, indicate that by stating "none". Separate each letter with a space. Hint: Determine the difference in the distance that each wave travels from the point sources. For example the difference between the distance travelled to B = 1.5λ - 0.5λ. Constructive interference occurs at ΔL=nλ. Destructive occurs at ΔL=nλ/2. B. List all the labeled points where the waves from the two sources destructively interfere. If there are no such points, indicate that by stating "none". Separate each letter with a space. Hint: Constructive occurs at ΔL=nλ. Destructive occurs at L=ΔL=nλ/2.

Determine if each sentence is True or False. If false, please explain a) All waves carry energy, and subsequently momentum as well.b) For sinusoidal waves, the kinetic and potential energy for a full wavelength are the same!c) For sinusoidal waves, the total energy does NOT depend of the frequency of the wave.d) The power of a wave depends on the speed of the wave; the faster the speed, the more power in the wave. Themeans waves on a sting under with more tension will always deliver more power than waves on a sting with lesstension.
