HROTY TULO TUGU UN Review Part A The pocket of hot air appears to be a pool of water because NOUVY GRY I SUOI a sunny day. A small, distant dip in the road appears to be filled with water. You may even see the reflection of an oncoming car. But, as you get closer, you find no puddle of water after all; the shimmering surface vanishes, and you see nothing but empty road. It was only a mirage, the name for this phenomenon. The mirage is due to the different index of refraction of hot and cool air. The actual bending of the light rays that the mirage is subtle, but we can make a simple follows. When airi ris heated, its density decreases and so does its index of refraction. Consequently, a pocket of hot air in a dip in a road has a lower index of refraction than the cooler air above it Incident light rays with large angles of incidence (that is, nearly parallel to the road, as shown in (Figure 2)) experience total internal reflection. The mirage that you see is due to this reflection. As you get nearer, angle goes below the critical angle and there is no more total internal reflection: the "water" disappears! produces the model as the hot air emits blue light that is the same color as the daytime sky. a O its density is close to that of water. a Olight refracts at the boundary between the hot and cool air. Olight reflects at the boundary between the hot and cool air. Submit Request Answer Figure 1 of 2 > Part B Which of these changes would allow you to get closer to the mirage before it vanishes? O Looking for the on a windy day, which mixes the air layers. Looking at it from a greater height above the ground. Making the pocket of hot air nearer in temperature to the air above it. Increasing the difference in temperature between the pocket of hot air and the air above it. Submit Request Answer
