- Two light pulses are emitted simultaneously from a source. Both pulses travel through the same total length of air to a detector, hut mirrors shunt one pulse along a path that carries it through an extra length of 6.20 in of ice along the way. Determine the difference in the pulses times of arrival at the detector.arrow_forwardIn placing a sample on a microscope slide, a glass cover is placed over a water drop on the glass slide. Light incident from above can reflect from the top and bottom of the glass cover and from the glass slide below the water drop. At which surfaces will there be a phase change in the reflected light?arrow_forwardWhich is true of diffraction? (7.6) (a) It occurs best when the slit width is less than the wavelength of a wave. (b) It depends on refraction. (c) It is caused by interference. (d) It does not occur for light.arrow_forward
- From his measurements, Roemer estimated that it took 22 mm for light to travel a distance equal to the diameter of Earth’s orbit around the Sun. (a) Use this estimate along with the known diameter of Earth’s orbit to obtain a rough value of the speed of light. (b) Light actually takes 16.5 mm to travel this distance. Use this time to calculate the speed of light.arrow_forwardThe speed of a water wave is described by v=gd, where d is the water depth, assumed to be small compared to the wavelength. Because their speed changes, water waves refract when moving into a region of different depth. (a) Sketch a map of an ocean beach on the eastern side of a landmass. Show contour lines of constant depth under water, assuming a reasonably uniform slope. (b) Suppose waves approach the coast from a storm far away to the northnortheast. Demonstrate that the waves move nearly perpendicular to the shoreline when they reach the beach. (c) Sketch a map of a coastline with alternating bays and headlands as suggested in Figure P34.26. Again make a reasonable guess about the shape of contour lines of constant depth. (d) Suppose waves approach the coast, carrying energy with uniform density along originally straight wave fronts. Show that the energy reaching the coast is concentrated at the headlands and has lower intensity in the bays.
