Light reflecting from the fisherman refracts at an angle of 50 degrees from the normal. Does the fish see the fisherman, or does it see the reflected view of the starfish at the bottom of the pond.
(a) Light reflecting from the fisherman refracts at an angle of 50 degrees from the normal. Does the fish see the fisherman, or does it see the reflected view of the starfish at the bottom of the pond.
(b) These fish scales reflect light at a water wavelength of 528 nm. The fish scales are primarily made of guanine of index of refraction 1.8 and underneath the fish scale is the cytoplasm of index of refraction close to water, 1.33. How thick are the fish scales?
(c) The fisherman is bothered by the light reflecting off the pond. The intensity is about 3.2W/m2. He calculates that it will take the sun some time to set at an angle such that the light reflected is less intensity or 100% polarized. What is the angle?
(d) The fisherman is finally able to catch the fish, but he first wants to make sure he caught the correct fish before reeling the fish further from the surface of the water. He leaves the fish right above the water at the end of the fishing line 100 cm away from him. He pulls out a convex lens with focal length of 35 cm and extends it 30 cm from him. How magnified is the final image of the caught fish?
