Fiber optics are an important part of our modern internet. In these fibers, two different glasses are used to confine the light by total internal reflection at the critical angle for the interface between the core (ncore = 1.491 ) and the cladding (n cladding = 1.436). Required:
What is the largest angle (in degrees) a ray will make with respect to the interface of the fiber max, and still experience total internal reflection?

The mantle is made up of which structural zones?

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.

What causes the development of most clouds and precipitation in the atmosphere?
