You are standing at the edge fo a swimming pool and shining a laser pointer onto the water surface. The laser beam hits the water at an angle of 50.8 deg above the horizontal. Some of the lights reflects off the water surface, and some enter the water. Find the angle between the reflected and refracted rays. From Snell's law I got the refracted angle of the laser beam= 35.64 deg. Then I thought it was just the difference between...

5. Unpolarized light from the Sun reflects from the surface of water (n = 1.33). At what angle of incidence (relative to the normal) does the reflected light become completely polarized? Draw this scenario and indicate the direction of polarization of the reflected ray (remember you can use a O, or an® to represent polarization perpendicular to the page). 6.

A manganese vapor laser beam is reflected from the surface of a CD onto a wall. The brightest spot is the reflected beam at an angle equal to the angle of incidence. However, fringes are also observed. If the wall is 1.6 m from the CD, and the first bright fringe is 0.551 m from the central maximum, what is the spacing (in m) of grooves on the CD? (Assume a manganese vapor laser has a wavelength of 534 nm....

3a. Light traveling in air encounters a flat side of a solid block of a transparent material that is completely immersed in air, i.e., it is completely surrounded by the air. Some of the incident light is reflected back into the air and some enters the material. If the angle of incidence that the light makes at the flat side is 16.8 degrees, what is the angle that the light is reflected back into the air relative to a perpendicular...
