A ray of light travelling through air encounters a 1.7-cm-thick sheet of glass at a 45 ∘ angle of incidence. Assume n = 1.5. How far does the light ray travel inside the glass before emerging on the far side?Express your answer in centimeters.

A beam of light enters from air into a slab of glass (nglass=1.5) along a surface tilted at a 45 degree angle from the horizontal. What is the angle?

Optical fibers are a central part of technology for rapid information transmission with a high level of efficiency. A new type of optical fiber is crafted with an index of refraction n = less than that of water in the vicinity of room temperature, where NH2O fact that n < nH20 potentially problematic if the fiber should be submerged? 1.25 = 1.33. Why is the O A. Total internal reflection would be frustrated, allowing loss of signal. O B. Internal reflection would actually be enhanced, so there is no problem. C. Electric eels might have free internet access.

A light beam containing red and violet wavelengths is incident on a slab of quartz at an angle of incidence of 51.00°. The index of refraction of quartz is 1.455 at 660 nm (red light), and its index of refraction is 1.468 at 410 nm (violet light). Find the dispersion of the slab, which is defined as the difference in the angles of refraction for the two wavelengths. °
