Chrichment lamp light Reflective Angle 30 When a beam of light strikes a mirror, it is reflected at the same angle as it hits. The diagram on the right shows how the light from the lamp strikes the mirror at a 30° angle. It reflects into the boy's eye at the same level. 30 reflected light Alvin Alvin knows about the reflective angles of a mirror. He decides to use this method to measure the height of the building to see how long a ladder will be for him to reach the roof. Alvin has a mirror and a meter stick. 1 Find the similar triangles in the illustration. 2, What measurements does Alvin have to make? Oロロロ 3. Assign some measures to your illustration. Let x be the height of the building. 4. Write the proportion and solve for x. 5. Look for the tallest tree in your school campus and find its height using the method presented above. Mrin Facus

An object is placed 10 m before a convex lens with focal length 5.2 m . Another concave lens is placed 15.6 m behind the first lens with a focal length −7.2 m (see the figure below). Note: Make a ray diagram sketch in order to check your numerical answer. At what distance is the first image from the first lens? Answer in units of m. What is the magnification of the first image? At what distance is the second image from the second lens? Answer in units of m. What is the magnification of the final image, when compared to the initial object?

Two mirrors intersect at an angle of 45°. If incident light strikes mirror 1 at an angle of 60°, what is the direction of the ray after striking mirror 2? (That is, what is the angle below the horizontal ??)You may want to redraw this figure so that you can see the triangles that help you find the angle needed.
A 1.5 cmcm high object is located 30 cmcm from a diverging lens, whose focal length is 11 cmcm . What is the height of the image produced by the lens? You have determined the height of the image using numerical methods and, in so doing, have also determined its position, s′s′s'. Now, use graphical methods to evaluate your results.The diagram below shows the object, a ray (ray 1) parallel to the optic axis of the lens, and a ray (ray 2) proceeding toward the first focal point of the lens. Draw the refracted rays and the image produced by the lens. Make sure you extend the refracted rays sufficiently backward in order to find the image. Keep in mind that principal-ray diagrams must be drawn accurately to give good results!
