water interface (the surface of the lake), it is partly
reflected back into the air and partly refracted
or transmitted into the water. This explains why on the surface of
a lake sometimes you see the reflection of the surrounding
landscape and other times the underwater vegetation.
These effects on light propagation occur because light travels at
different speeds depending on the medium. The index of refraction
of a material, denoted by n, gives an indication of the speed of...

P3. A light ray of wavelength 589 nm traveling through air is incident on a smooth, flat slab of crown glass gas1.52) at an angle of 30.0° to the normal. At a boundary between air and glass, light is partially eflected and partially refracted. z Reflected P3d [2 points] At whial angle of incidence will the light reflected from the slab be completely polarized?

Project (2) Read the manual When unpolarized light is incident on the surface of (say) glass at the Brewster angle, the reflected light is polarized with its polarization parallel to the surface of the glass. The Brewster angle is given by Tan(O) = n where n is the refractive index of glass. The material need not be glass; it could be plastic, water etc. (any smooth transparent material is fine). Exercise: (1) The Brewster angle in the experiment is found...

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...

A light ray entering an optical fiber (made from crown glass) surrounded by air is first refracted and then reflected as shown below 2 1 a. What is the minimum angle 01 (greater than or equal to 0) at which an incident ray will still be totally internally reflected? Hint for (a) Minimum angle 61 deg. (Only enter values 0 or greater.) b. What is the maximum angle 61 (smaller than 90 deg) at which an incident ray will still...
