Two sources emit identical waves in phase with each other. What is the largest wavelength that will result in constructive interference when the observer is 134 m from one source and 182 m from the other? What is the largest wavelength that will result in destructive interference in this situation?

Two stones are dropped simultaneously into a pond 1.65 m apart and 19.1 m away from the straight edge of the pond. They produce waves of wavelength 0.28 m. The two waves meet and interfere along the pond’s edge. At the symmetric middle point P0 the interference is constructive. The next three constructive interference sites are denoted P1, P2, and P3. Refer to figure. This is not a small-angle situation, although you may still assume that the stones are dropped close together relative to the distance of the edge of the pond.   a. What is the distance, in meters, between P1 and P0?  b. What is the distance, in meters, between P2 and P0?  c. What is the distance, in meters, between P3 and P0?

An ultrasonic wave travels from tissue (n=1.4) into bone (n=2.0) striking the boundary at an incident angle 46.  What is the angle of refraction?

A very thin oil film (n=1.25) floats on water (n=1.33). What is the thinnest film (but not zero) that produces a strong reflection for green light with a wavelength of 500  nm?Express your answer in nanometers.

Two identical point sources are 5.0 cm apart, in phase and vibrating at a frequency of 12 Hz. They produce an interference pattern. A point on the first nodal line is 5 cm from one source and 5.5 cm from the other. Determine thewavelength and the speed of the waves.

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?…

Two waves, D1(x,t) = A sin (kx - wt + 5n/6) and D2 = A sin (kx - wt + n) are %3D superimposed. The two waves will interfere The amplitude of the superposed wave is times A (where A is the amplitude of the original wave)

A carousel that is 6.00m in radius has a pair of 600Hz sirens mounted on posts at opposite ends of a diameter. The carousel rotates with an angular velocity of 0.900rad/s. A stationary listener is located at a distance from the carousel. The longest wavelength reaching the listener from the sirens is closest to
