If we make an object shadow on the wall, it will appear some shadows. The picture shows the wave properties i.e ... a) dispersion b) reflection c) diffraction d) polarization e) interference

2) A wave moves from medium n₁ to medium №2. a) Write the expressions for the coefficients of transmission and reflection for the case of normal incidence using that μ can be approximated as μo for both mediums. b) Using the results from the previous part, find the intensity of the incident and reflected wave in terms of n₁, n₂ and the intensity of the transmitted wave IT. c) Check that if n₁ n2, we get that IR = 0 and I₁ = IT.

A narrow beam of ultrasonic waves reflects off the liver tumor in the figure below. If the speed of the wave is 15.8% less in the liver than in the surrounding medium, determine the depth of the tumor. cm 12.0 cm 50.00! Liver Tumor

A narrow beam of ultrasonic waves reflects off the liver tumor in the figure below. If the speed of the wave is 10.3% less in the liver than in the surrounding medium, determine the depth of the tumor. cm

courses / PHYS1211 / Assessment Activity 2- Quizzes/ Quiz -1 Wave A A Wave BAAA Name the type of interference, the waves A and B show and why? Answer: destructive interference because they are 180° out of phase with each other constructive interference because they are in-phase with each other destructive interference because they are in-phase with each other constructive interference because they are 180° out of phase with each other

Solve the following exercises related to the topics of waves, placing an image or drawing where they represent the problem posed: 1.- What is the illumination produced by a 120 cd lamp on a perpendicular surface located at a distance of 2.5 cm? 2.5 cm away? 2.- A lamp in a classroom has an intensity of 250 cd, what is the illumination that it produces on a notebook, if there is a distance of 3m and an angle of 45º between them? 3.- Calculate the frequency and period of the waves produced on a guitar string, if they have a propagation speed of 140 m/s and their wavelength is 0.3 m/cycle. *Place a diagram or drawing representing with the data the given problem.   Thank you very much for your help! :)
