13. In a two-point source interference pattern in a ripple tank, a point is one wavelength farther from one source than the other. If the two sources are in phase, then there is a. destructive interference at this point b. constructive interference at this point c. both constructive and destructive interference simultaneously d. neither constructive nor destructive interference at this point e. no interaction between the two waves at this point 14. A student wishes to perform Young's double-slit experiment to measure the wavelength of light of a given source. The student has measured the average distance between adjacent dark bands and the distance from the slits to the screen. What other measurement is required to calculate the wavelength? a. the location of the central bright line b. the distance between the source and the slits c. the angle between the central bright line and first nodal line d. the distance separating the two slits e. the distance between the centre of the two slits and any given dark band 15. Two monochromatic point sources of light, S, and S2, are shown below. They are initially in phase. Screen $2 As the phase of S₁ is increasingly delayed with respect to S2, which of the following would be observed? a. The interference pattern will slowly disappear. b. The distance between adjacent dark bands will increase. c. The distance between adjacent dark bands will decrease. d. The pattern of dark bands will slowly begin to shift. e. The central maximum will become twice as wide. 16. In Newtonian mechanics, the speed of light a. is 3 x 108 m/s b. can be infinite c. will be slower than c 17. The equation E=mc² illustrates that d. will be faster than c e. none of the above a. travelling at the speed of light converts matter into energy b. rest mass and energy are equivalent C. energy can be converted into mass d. matter can be converted into energy e. both b and d 4 of 13
