A beam of light in air is incident on a stack ofsix at transparent materials with indices of refraction 1.20,1.40,1.32, 1.28, 1.26,1.43. If the angle of incidence for the beam on the top of the first of the four materials is 650 a. Draw a diagram of this scenario. b. What is the angle of refraction in the first material? c. What angle does the beam make to the normal when it emerges from the air after passing through the entire stack? To view a mushroom, a middle school child attempts to magnify it using a concave mirror with R=75 cm. The child places the mushroom at a distance of 25 cm from the vertex. The mushroom is 2.3 cm tall. a. Draw a ray diagram b. What is the image distance? C. Is the object upright or inverted? d. What is the magnification? e. What is the height of the image? f. Did the child succeed in magnifying the image
