how to solve it ?
A20. Two identical sound sources emit sound waves of wavelength 2 and are separated by a distance d. What is the lowest non-zero value of d for which constructive interference occurs everywhere along the line that passes through the two sources? Consider only points which do not lie between the two sources. A. 2 B. λ/4 С. 2 D. λ/2 E. 4λ

B. Describe what happens at a point on the surface of the water where: • a crest meets a crest . . a trough meets a trough a crest meets a trough For each of the above cases, describe how your answer would differ if the amplitudes of the two waves were not equal. Explain your reasoning. If the waves from two identical sources travel different distances to reach a particular point, the amplitudes of the waves from...

Combinations of Thin Films (MC) Due in 2 hours, 18 minutes The diagram shows light incident from above on a film of thickness d. Each of the three materials in the figure can be chosen to be air, with index of refraction n-1.00, water, with index n-1.33, or glass, with index n-1.50. Under which of the following conditions will the reflected light be completely or nearly eliminated by interference? (lambda2 refers to the wavelength of the light inside the thin...

EXPERIMENT 10 THIN FILM INTERFERENCE Light from a monochromatic source is shined downward on two glass plates that are separated at one end by a hair. Light that is reflected from the top and bottom surfaces of the wedge-shaped thin film of air undergoes interference, and a series of dark and light lines are seen. By counting the number of dark or light lines over a known...
