Two plane mirrors are separated by 120°, as the drawing illustrates. If a ray strikes mirror M₁ at a 65° angle of incidence, at what angle does it leave mirror M₂? Number Units M₁ + 120 M2

The drawing shows a rectangular block of glass (n = 1.52) surrounded by a liquid with n = 1.75. A ray of light is incident on the glass at point A with a 30.0° angle of incidence. At what angle does the ray leave the glass at point B? Number i Units 4

A mirror is placed perpendicular to a swimming pool water surface. A narrow beam of light incident on the mirror is reflected on the mirror and then it follows the path shown in the figure. The angle of incidence on the mirror is 0₁ = 25.0°. Find the (a) 1 and water = = 1.33) angle of incidence, 02 on water surface; (b) the angle of refraction, 03 in water. (nair = mirror water 0₂ Your answer (a) 0₂ ; (b) 03.

For an independent study project, you design an experiment to measure the speed of light. You propose to bounce laser light off a mirror that is 55.0 km due east and have it detected by a light sensor that is 123 m due south of the laser. The first problem is to orient the mirror so that the laser light reflects off the mirror and into the light sensor. (a) Determine the angle that the normal to the mirror should make with respect to due west. (b) Since you can read your protractor only so accurately, the mirror is slightly misaligned and the actual angle between the normal to the mirror and due west exceeds the desired amount by 0.005°. Determine how far south you need to move the light sensor in order to detect the reflected laser light. Additienel Meteriele

In the figure the laser beam strikes the first mirror M1 at a point 11.5 cm from the corner point (point of intersection of two mirrors).  Calculate the approximate angle of incidence at which the ray strikes the second mirror, if it strikes at  the midpoint of the second mirror (M2) 14.0 cm away from the corner point, after being reflected by the 1st mirror.

A ray of light strikes a flat block of glass at an incidence angle of ?1 = 38.6°. The glass is 2.00 cm thick and has an index of refraction that equals ng = 1.52.   (a) What is the angle of refraction, ?2,that describes the light ray after it enters the glass from above? (Enter your answer in degrees to at least 2 decimal places.)   b.)With what angle of incidence, ?3,does the ray approach the interface at the bottom of the glass? (Enter your answer in degrees to at least 2 decimal places.)

A layer of oil (n = 1.45) floats on an unknown liquid. A ray of light originates in the oil and passes into the unknown liquid. The angle of incidence is 60.9 degrees, and the angle of refraction is 69.2 degrees. What is the index of refraction of the unknown liquid?

Two plane mirrors are separated by 120°, as the drawing illustrates. If a ray strikes mirror M₁ at a 65° angle of incidence, at what angle 0 does it leave mirror M₂? 65° M₁ 1209 M₂

Two plane mirrors make the angle a = 58.0° between them. A ray of light incident on one of the mirrors is reflected and it hits the second mirror, as shown in the figure. Determine the angle ẞ between the ray incident on the first mirror and the ray reflected off of the second mirror. B = B
