What is the critical angle θcritθcrittheta_crit for light propagating from a material with index of refraction of 1.50 to a material with index of refraction of 1.00?

The critical angle is 41.8°.

Explanation:

The critical angle is for which the angle of refraction is 90°. From Snell's law we have

Putting in and we get:

Thus, the critical angle is 41.8°.

d) physical means can be used to separate the components of air.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
