Circular water waves are generated in a large ripple tank by two small objects that tap the surface of the water. These sources move up and down regularly and in unison (je., the sources have the same frequency and are in phase). The distance between the sources is 2.51, where A represents the wavelength of the waves generated by the sources. Point C -3004 - Point A 4004 Enlarged view of sources Point B Sources Top view For each of the lettered points: i. Determine whether there is maximum constructive interference, complete destructive Lerference, or neither at that point. ii. Find the phase difference between the waves from the two sources at that point. Explain. Clearly explain any approximations that you use. a. Point A 1. b. Point B ii. c. Point C i. H.The diagram from the front page is reproduced below. Point C 3004 Point A 400A 2.5A Enlarged view of sources Point B !Sources Top view 2. At which of the three lettered points would the water surface move the most? Explain.Light from a laser passes through two very narrow X Y Z slits as shown in the top-view diagram at right. The Pattern photograph shows what appears on a screen that is far on from the mask. The screen is bright at points X and Y screen and dark at point Z. Screen Two vertical slits (not shown) Mask Laser (aimed at slits in mask} Top-view diagram 1. In the box provided below right, show what would appear X Y Z on the same part of the screen if the left slit were covered. Explain your reasoning. Center of screen In particular, if the left slit were covered, would the brightness at each of the following points increase, decrease, or stay the same? Explain your reasoning in each case. a. point X b. point Y c. point ZA single change is made to the apparatus, resulting in the new pattern on the screen Original pattern on screen shown at right. For each of the following quantities, determine New pattern whether a change in that quantity could produce on screen the new pattern shown. If so: Should the quantity be increased or Center of screen decreased? Explain your reasoning. If not: Explain why not. a. the distance between the slits b. the wavelength of the laser light c. the width of both slits d. the distance from the mask to the screen
