Suppose a layer of oil no = 5/4 is floating on water nw = 4/3, that in turn is on a piece of glass ng = 3/2. Show that the critical angle for the glass is not changed by the combined system of layers of water and oil; that rays incident on the glass-water interface at or above the critical angle for glass-air alone do not escape the final layer of oil.

3. A thin layer of turpentine (n-1.472) is floating on water (-1.333). Light of wavelength 589 nm initially traveling in air is incident on the turpentine at an angle of 24.8° measured with respect to the air turpentine interface. b. c. After the light passes through the turpentine, what is its refraction angle in the water? At what angle should the light be incident on the turpentine-water interface so that all the light totally internally reflects in the turpentine and...

a. There is a uniform layer of linseed oil (n = 1.48) floating on top of water (n = 1.33). If a light beam is refracted so its angle in the linseed oil is 23.2 degrees, what is the angle of incidence from the air and the angle the light exiting toward the bottom of the water ? b. If you start with the same incident angle you computed in part a, but over time the oil vaporizes until it...

A light ray in air (n= 1) is incident on a thin film of oil (noil = 1.60) floating on top of water (nwater = 1.33), as shown below. The wavelength of the incident light in air is Aair = 640 nm. The oil layer has a thickness t = 0.5 um. The ray is assumed to be incident practically along the normal. That is, we won't be worried about angles of reflection or refraction when doing this problem. However,...

Partner: Date Name 11 Snell's Law Introduction When light passes from one material to another it is always bent away from its original path. This process is known as refraction and the change in direction depends on the change in optical density (or refractive index) of the two materials. A larger change in refractive index results in a larger change in angle between incoming and outgoing light beams. A light beam bends closer to the normal in the material with...
