An observer is at table level, a distance d to the left of a flower of height h. The flower itself is a distance d to the left of a mirror. Note that a ray of light propagating from the top of the flower to the observer's eye reflects from the mirror at a height y above the table. If the height y is equal to 20 cm, calculate the height h of the flower.

A beam of light reflects and refracts at point A on the interface between material 1 (n₁ = 1.33) and material 2 (n2 = 1.66). The incident beam makes an angle of 40° with the interface. What is the angle of reflection at point A?
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
A beam of light (angle θ₀=15°) inside a transparent material (n=2) hits the surface. Notice the change in subscripts of the angles. For example, the refraction angle is θt, for "transmitted", whereas θr is the "reflected" angle. Use the correct quantity, not necessarily the variable name. Calculate the transmitted (refracted) angle. Please see photo for more details.
