PHY MISC Lab 07 – Optics Latest
updated version with 100% accuracy-
South college
NAME:_______________
Time spent on Lab 07 = approximately 2 hours, does not need to be done at
one sitting Materials needed = Access to computer and high speed
internet, Java installed on the computer, a browser with Flash built-in
(likely Chrome is best)
Learning Objectives:
● Define how a light wave interacts with a physical medium and
construct laws which govern this interaction
Virtual Lab:
To begin this week’s lab, proceed to:

Figure #1
The screenshot shows a laser which is turned on, shining light from air to
water. If you drag the protractor so that the central point is over the laser
light when it hits the water, then you can measure the angles between the
laser beam and the normal (dashed line) on both side of the water.
1. Please go ahead and measure the angle between the incoming light
and the dashed line going up. Also, please measure the angle
between the light in the water, and the dashed line going down.
Write the answers below and comment on whether the angles
SHOULD be the same, different, in what way.
50 ,30 degrees The are different angulations because the light is passing
through the surface, that changes their speed and direction.
You may have already read in the textbook that Snell’s Law states that light
entering into a different substance, at some angle, will “refract” by some
