    #1-A prism with angles 45°, 45° and 90° is to be used to turn a beam of light through a 90° angle. What is the minimum index of refraction for the material of the prism that will give the total internal reflection needed?

    #2- A tarantula of height 2.0cm is sitting in front of a spherical mirror with focal length │F│= 4.0cm. The tarantula sees an image of itself that has a height of 0.40cm and appears upright. Is the mirror concave or convex and what are the characteristics of the image?

    (1) Here, the critical angle required is C < 45 deg

    sin C < sin 45

    1/mu < 1/sqrt 2

    mu > sqrt 2

    The minimum index of ...
