Question

Experiment 13 the second boundary of the semi-circular plastic container as the light For Home or Lab 1. Why is there no refraction at the second bour re-emerges from the water to the air? ion of diamond is 2.4. If the incident angle is 20°, what is the angle of 2. The index of refraction of diamond is 24 refraction? the setting sun comes through the earth's atmosphere along a curved path so that the sun looks higher in the sky than it really is. How do you explain this? Also, the setting sun appears to flatten somewhat. Because atmospheric refraction increases with objects near the horizon, the lower edge of the sun's disk is raised more than the upper edge. Illustrate this with a diagram.

Answer 1

rares 12. 4 = 24 , Li= 20 , Era ? suis = thing : Sin 20º = 0.1425 O Sinr r=8-2° . Sumo 3. As the rays of light comes from sun . to earth, the refractive inder of layers goes on increasing. Now, as the ray deviates terwards the do normal. As we see in line of sight, so the sun afhears higher. umowny
