Homework Answers
a. The wave propagation direction changes whenever a wave goes across a boundary
This is due to refraction phenomenon.
b. Whispering gallery effect is a result of diffraction
c. When two waves interfere constructively, the amplitude of the resultant wave changes with time
when two waves interfere constructively, the amplitude of the resultant wave is the sum of the amplitudes of individual waves

Select the statements that are TRUE regarding interference. Interference is a phenomenon that occurs for both particles and waves. When two waves interfere, the amplitude of the resultant wave is a combination of the amplitudes of the individual waves. Only transverse type waves like waves on a string or light waves can experience interference. | Interference occurs if two waves occupy the same position at the same time. Two waves must be coherent or they will not interfere with each...

Select the statements that are TRUE regarding interference. Two waves must be coherent or they will not interfere with each other. Only transverse type waves like waves on a string or light waves can experience interference. Two waves must both have spherical wavefronts in order to interfere with each other.

Indicate true or false in each of the following statements: A standing wave is the superposition of two waves The beating of two waves can be heard as a much higher frequency than the sum of the two frequencies. The second harmonic is twice times the frequency of the fundamental. Constructive interference occurs when the phase difference of two otherwise identical waves is 2π or multiples thereof. A node is a position on a standing wave of maximum displacement

To gain an understanding of constructive and destructive interference.
Consider two sinusoidal waves (1 and 2) of identical wavelength ?, period T, and maximum amplitude A. A snapshot of one of these waves taken at a certain time is displayed in the figure below. (Figure 1) Let y1(x,t) and y2(x,t) represent the displacement of each wave at position x at time t. If these waves were to be in the same location (x) at the same time, they...

Which of the following statements is (are) TRUE? 1A two-way table is a useful way to summarize data when two categorical variables are measured on the same individuals or cases. 2Simpson’s paradox is an example of the potential effect of a lurking variable on an observed association between two categorical variables. 3If the counts in each cell of a two-way table are divided by the total number of observations, the result is the joint distribution of the two categorical variables....

Example 18.7 The Mistuned Piano Strings Two identical piano strings of length 0.775 m are each tuned exactly to 400 Hz. The tension in one of the strings is then increased by 1.0%. If they are now struck, what is the beat frequency between the fundamentals of the two strings? SOLVE IT Conceptualize As the tension in one of the strings is changed, its fundamental frequency changes. Therefore, when both strings are played, they will have different frequencies and beats...
