Medium 1 (n₁ = 1.37) and medium 2 (n₂= 4.80) are two rectangular- shaped layers stacked together. An incident ray in medium 2 makes a right triangle with sides AB and BC; AB is along the normal direction of the interface. If the height of AB is h = 8.8 m, what is the minimum distance of BC (unit in meters) that will result in total internal reflection at the interface?

Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.

Question

Medium 1 (n₁= 1.37) and medium 2 (n₂= 4.80) are two rectangular-
shaped layers stacked together. An incident ray in medium 2 makes a
right triangle with sides AB and BC; AB is along the normal direction
of the interface. If the height of AB is h = 8.8 m, what is the minimum
distance of BC (unit in meters) that will result in total internal
reflection at the interface?

A goldfish is swimming inside a spherical bowl of water having an index of refraction n = 1.333. Suppose the goldfish is p 10.4 cm from the wall of a bowl of radius |R| = 15.8 cm, as in the figure below. Neglecting the refraction of light caused by the wall of the bowl, determine the apparent distance of the goldfish from the wall according to an observer outside the bowl. 1.07 Your response differs from the correct answer by more than 10%.

The figure depicts a simplistic optical fiber: a plastic core (n₁ = 1.58) is surrounded by a plastic sheath (n₂ = 1.46). A light ray is incident on one end of the fiber at angle 8. The rays is to undergo total internal reflection at point A, where it encounters the core-sheath boundary. (Thus there is no loss of light through that boundary.) What is the maximum value of that allows total internal reflection at A?

White light strikes the left face of a 300-60°-90° glass prism along a normal to the surface (so there is no refraction there).
