In a michelson type experiment, the rotating 8 sided mirror spins at 30 000 revolutions per minute. The reflecting plane mirror is 32.4 km away. The speed of light determined using this data is what?

What is the speed of light inside a high-index lens that has a refraction index (n) of 1.70?

A ray of light is directed toward the surface of a block of fused quartz at an angle of 29.0° with respect to the normal (a line perpendicular to the surface at the spot where the ray hits the block). A fraction of the light is reflected and the rest refracted. What is the angle (in degrees) between the reflected and refracted rays?

Consider a Fizeau experiment in which the wheel has 450 notches and rotates with a speed of 35 rev>s. Light passingthrough one notch travels to the mirror and back just in time to pass through the next notch. If the distance from thewheel to the mirror is 9500 m, what is the speed of light obtained by this measurement?

What is the value for the constant for the speed of light?

The index of refraction in a plastic rod is 2.59.  What is the speed of light in this plastic rod (in meters per second)? Write your answer in Scientific Notation.

For problem 57, calculate the diameter of the circle in cm at the surface if the depth of the light source is 64.7 cm (5 sig figs)

Race rocket driver Suzy is heading down the final straightaway, approaching the finish line at 1.0 x 108 m/s. Her fans, at the finish line straight ahead, are shooting laser beams toward her (but not into her eyes). The speed of light is 3.0 x 108 m/s. How fast are the light waves approaching in Suzy's reference frame? 3. a) Light waves do not travel in Suzy's frame. b) 1.0 x 10² m/s c) 3.0 x 108 m/s d) 4.0 x 10² m/s

The speed of light in a particular type of glass is 1.40  108 m/s. What is the index of refraction of the glass?

Two plane mirrors are facing each other. They are parallel, 2 cm apart, and 24 cm in length, as the drawing indicates. A laser beam is directed at the top mirror from the left edge of the bottom mirror. What is the smallest angle of incidence with respect to the top mirror, such that the laser beam hits the mirrors in each way? Laser (a) hits only one of the mirrors (b) hits each mirror only once 1,316 étv (A 20 MacBook Air 80 F7 F5 F6 esc F2 F3 F4 F1 & @ #3 2$ 1 3 4 ト
