Name: _ 4. A concave mirror with a center of curvature at 12.4cm has an object that is 5.6cm from the mirror. a. Determine the location of the image. b. Determine the magnification of the mirror. c. If the height of the image is 4.5cm, determine the original high of the object. 5. A light ray strikes an air/glass surface at an angle of 350 with respect to the normal. The refraction index for glass is 1.52. Determine the angle of refraction when the direction of the ray is going from a. Air to glass b. Glass to air c. Determine the critical angle for the pair. What direction will TIR occur (from what to what)
