Calculate the intensity pattern near a perfectly reflecting mirror. Assume that wave falls on the mirror at normal incidence. Express your answer for I(x) where x is the distance from the mirror. The waves have unequal amplitudes but the same frequency and wavelength. There is also a phase shift between the two waves.

Homework 6-(Week 11, Lab) Submission deadline, 04/14/2019 at 9pm Problem 1: An interferometer is an instrument that uses the interference patterns formed by waves (usually light, radio, or sound waves) to measure certain characteristics of the waves themselves or of materials that reflect, refract, or transmit the waves. Interferometers can also be used to make precise measurements of distance. Depending on the path difference, it is possible to create constructive interference (where the strength of two waves are added), destructive...

1) A block oscillates back and forth horizontally on a table due to being attached to spring. The block travels the fastest when the spring is most stretched. Answer 2) A block oscillates back and forth horizontally on a frictionless table due to being attached to spring. The frequency of oscillation would be smaller if a more massive block was used. Answer 3) Two longitudinal waves with different amplitudes are observed. The wave with the greatest intensity...

Learning Goal: To understand de Broglie waves and the calculation of wave properties. In 1924, Louis de Broglie postulated that particles such as electrons and protons might exhibit wavelike properties. His thinking was guided by the notion that light has both wave and particle characteristics, so he postulated that particles such as electrons and protons would obey the same wavelength-momentum relation as that obeyed by light: λ=h/p, where λ is the wavelength, p the momentum, and h Planck's constant. Part...

2 A Lloyd's mirror experiment is carried out using a coherent beam of thermal neutrons. In this experiment the neutrons are able to travel over two paths to a detector D, as shown in Figure 1 One path proceeds directly from the neutron source S, through a phase shifter PS to the detector D, whilst the second path requires the neutrons to reflect off a perfect silicon mirror M, before...

To understand polarization of light and how to use Malus's law to calculate the intensity of a beam of light after passing through one or more polarizing filters. The two transverse waves shown in the figure(Figure 1) both travel in the +z direction. The waves differ in that the top wave oscillates horizontally and the bottom wave oscillates vertically. The direction of oscillation of a wave is called the polarization of the wave. The upper wave is described as polarized...

12. A longitudinal standing wave can be created in a long, thin aluminum rod by stroking the rod with very dry fingers. This is often done as a physics demonstration, creating a high-pitched, very annoying whine. From a wave perspective, the standing wave is equivalent to a sound standing wave in an open-open tube. In particular, both ends of the rod are anti-nodes. What is the fundamental frequency of a 2.50 m -long aluminum rod? The speed of sound in...
