Musical Notes:

“Over the Rainbow” is the classic ballad song from the 1939 movie, The Wizard of Oz.  It was originally sung by actress Judy Garland.  Here is my favorite version sung by Israel Kamakawiwoʻole, a famous Hawaiian musician, in which he creates a medley of “Over the Rainbow” and “What a Wonderful World.”

    Hi Tiff,
    Light travels slower in water than air, right? Does it have to do with density?

      Do you mean how to draw the normal? You need to look at where the incident rays hit the mirror. Draw a straight line matching the curve of where the incident ray hits the mirror. Then use that straight line to draw the normal which is at a 90 degree angle. From there, you can measure the angle of incidence and then draw the reflected ray.
