NOTE: The values GIVEN HERE (***) are NOT ALL the same as the values attached. For all parts of this problem, assume: *** Relative to the medium of air, these waves travel at a speed of 400 m/s. *** Relative to the source, both these waves and these particles are emitted at a frequency of 800 Hz. *** Relative to the source, these particles travel at a speed of 400 m/s. a. Assume Waves are transmitted from Source to Receiver. Assume the Source is RECEDING from the Receiver at a speed of 80 m/s relative Assume that the Receiver is stationary relative to the Air. the Air. i. Draw a diagram of the situation as you understand it, making sure to label all values and making absolutely sure to explicate the direction. ii. As measured by the Source (relative to the Source), what is the velocity of these waves? iii. As measured by the Source, what is the wavelength of these waves? iv.

Consider the speaker set-up in the previous question. Each speaker emits a frequency of 6.6·102 Hz in phase with the other. The listener is seated directly in front of one speaker, 1.6 m away. The speakers are 2.4 m away from each other. How many extra wavelengths are needed for sound to get from speaker 2 to the listener? Take the speed of sound in air to be 3.4·102 m/s.

D. 2.00 2. In a Michaelson interferometer, a 4-sided mirror rotates in place. A laser beam strikes the rotating mirror and travels 100 m to a stationary mirror, which reflects the beam back. What is the smallest frequency required to rotate the mirror so that the reflected beam follows the same path as if the mirror was not rotating? A. 1.50 x 106 Hz B. 3.00 x 106 Hz C 3.75 x 105 Hz D. 7.50 x 105 Hz R L loom S
The speaker depicted below (See slide 10 of chapter 16 for a detailed explanation) emits a sound of frequency 779 Hz. Due to the path difference (r2 - r1) the receiver detects a constructive interference. Find the distance by which r2 needs to be adjusted to detect the very next destructive interference. (Take speed of sound as 343 m/s).
Speaker 1 is at x = 0 and speaker 2 is to the right and facing it at x = 3 m. The speakers are to the same amplifier, which plays a tone of unknown frequency. If the first point of destructive interference is 0.18 m to the left of the center, find the frequency in Hz. The speed of sound is 345 m/s. connected continuous f = Hz
