Question: If glass is dispersive why don t we normally see a
If glass is dispersive, why don’t we normally see a spectrum of colors when sunlight passes through a glass window? Explain. (Are the speeds of each color of light the same in the glass?)
Answer to relevant QuestionsWhen you see the Sun over a lake or the ocean, you often observe a long swath of light (Fig. 22.22). What causes this effect, sometimes called a “glitter path”? The indices of refraction for zircon and fused quartz can be found in Table 22.1. (a) The speed of light in fused quartz is (1) greater than, (2) less than, (3) the same as the speed of light in zircon. Explain. (b) ...A beam of light in air is incident on the surface of a slab of fused quartz. Part of the beam is transmitted into the quartz at an angle of refraction of 30o relative to a normal to the surface, and part is reflected. What ...What percentage of the actual depth is the apparent depth of an object submerged in oil if the observer is looking almost straight downward? A coin lies on the bottom of a pool under 1.5 m of water and 0.90 m from the side wall (Fig. 22.28). If a light beam is incident on the water surface at the wall, at what angle relative to the wall must the beam be directed ...
