Support high index of refraction Answer Question 6 (1 points) In the figure shown, the lighter medium is air and the darker medium is an unknown substance. What is the index of refraction of that substance? Note that the angles are given relative to the boundary surface. Remember to sketch a normal line!

Make sure to read all the instructions and answer each part. A beam of white light goes from air into crown glass at an incident angle of 750 to the normal. Use the table in Section 6.9 of your Kudu textbook to answer the following questions. Part a (1 points) What is the difference in the outgoing angle of the red light and the blue light as they penetrate into crown glass? Give your answer as a positive number in degrees. (Assume the red light has wavelength 660nm and the blue light has wavelength 470nm as given in the table). Please enter a numerical answer below.

How far in front of a convex mirror should an object be placed so as to form an image with magnication 2/3? Give your answer as a positive multiple the focal length lfl of the mirror. Note: The simulation is useful to help develop your intuition for curved mirrors. However, this is question is meant to be solved through mathematical equations and should not be just estimated from the simulation (which, of course, will not be available on an exam).
