The pipe shown is 2.75 m long. a. How many wavelengths appear in the pipe? b. Calculate the frequency of the standing wave shown in the pipe. c. In the blank pipe at the far right, sketch the wave shape of the 7th harmonic.

Two identical point sources are generating waves with the same frequency and amplitude.  The two sources are in phase with each other, so the two sources generate wave crests at the same instant.  The wavelength of the waves is equal to the distance between the two sources.   A. List all the labeled points where the waves from the two sources constructively interfere.  If there are no such points, indicate that by stating "none".  Separate each letter with a space.  Hint: Determine the difference in the distance that each wave travels from the point sources.  For example the difference between the distance travelled to B = 1.5λ - 0.5λ.  Constructive interference occurs at ΔL=nλ.  Destructive occurs at ΔL=nλ/2.   B. List all the labeled points where the waves from the two sources destructively interfere.  If there are no such points, indicate that by stating "none".  Separate each letter with a space.  Hint: Constructive occurs at ΔL=nλ.  Destructive occurs at L=ΔL=nλ/2.

21. Wave A and B are traveling towards each other on a rope as shown in the diagram to the right. Which statement describes the amplitude of the resultant wave when Wave A and B overlap? a. The resultant wave will have no amplitude b. The resultant wave will have a greater amplitude than both waves c. The resultant wave will have a smaller amplitude than both waves d. The resultant wave will have a great amplitude than Wave A but a smaller amplitude than Wave B

A standing transverse wave is formed in a string that is 5.0 m long. Both ends of the string are fixed. Eight loops are present in the standing wave 1. Draw the standing wave. Label one node and one antinode. 2. Find the wavelength of the wave. Fully explain how you found the wavelength. 3. If it takes a wave 0.60 s to travel the length of the string, find the speed of the wave. 4. Find the frequency of the wave.

3.Which graph shows a linear relationship?   The frequency is linear when plotted as a function of inverse length (ff vs. 1/L1/L). The frequency is linear when plotted as a function of length (ff vs. LL). 4.Draw a best-fit line through the linear graph’s data, and use the slope of this line to determine the wave speed. Express your answer in meters per second to two significant figures.
