Part (a) Superposition occurs during which of the following? Select all that apply. MultipleSelect: 1) When a single transverse wave is created with no reflections. 2) When waves pass through one another. 3) When a single transverse wave is created with reflections. 4) Only when smaller waves combine to create larger waves. Part (b) True or False: Destructive interference is the result of superposition of waves in phase. TrueOrFalse : 1) 2)

Two speakers are in phase and produces the same frequency as shown. The smallest frequency for which no sound is heard at Point P is: a) 100 Hz b) 200 Hz c) 500 Hz d) 1000 Hz e) 1500 Hz

Define each of the following wave phenomena, and give anexample of where each occurs: (a) refraction; (b) diffraction;(c) dispersion; (d) interference.

We know that a speaker that is 3m away from us is playing music at an intensity of 0.89W/m2. What is the power of this speaker?               Another speaker is playing at an intensity of 1.2W/m2 and a power of 2W. How far away is this speaker from us?                 What is the difference between constructive and destructive interference? Give an example of each.                   If you know that the interference of 2 waves creates a wavelength of a wave is 4.5m, can you determine if the interference is constructive or destructive? How do you know?             If one note has a frequency of 132Hz and another has a frequency of 148Hz. What is the beat frequency?     A vocal tract has a length of 15.3cm and is represented by the 3rd harmonic. 6a. How many nodes are there in the 3rd harmonic?         6b. What is the wavelength of the 3rd harmonic?               6c. What is the frequency of the 3rd harmonic?                 6d. What is the wavelength of the 4th harmonic?…
