Reflection and Refraction of Light
In this activity, the properties of reflection and refraction of
light will be explored. The simulation shows the light rays as they
are incident on a medium interface (incident ray), the reflected
from the medium interface (reflected ray), and refracted into the
second medium after crossing the interface (refracted ray).
Additionally the angles made by each of these rays with respect to
the normal (vertical black perpendicular to the interface) are
displayed as wedges in...

In a double slit interference measurement,the 2nd diffraction
minimum coincides with the m=9 interference maximum. Light 530nm in
wavelength is used, and the distance between the slits and the
screen in 1.1m, the slit width is 4μm. (a) How many full
interference bright fringes can you see within the main diffraction
envelope. (b) Find the slit separation? (c) What is the
inter-fringe distance? (d) One of the slits is covered with a thin
piece of transparent materia lof index of...
Interference Colors
(a) Why is reflection from a soap film much like reflection
from an oil layer? How is it different?
(b) With reference to the interference color in reflected
light, a very thin soap film is sometimes called a “black film”.
Why would it have a name like that? Is there such a thing as a
“white film”?
1. What does diffraction mean?
2. When does diffraction occur?
3. When looking at an interference or diffraction pattern, what
does an anti-node look like?
4. When looking at an interference or diffraction pattern, what
does a node look like?
5. What safety precautions are important to keep in mind while
you're using a laser pointer?
U22P1 In the reflection and refraction lab a beam of white light
is passed through a prism at an angle of 30 and separated into a
spectrum. The red portion of the spectrum is measured to be at an
angle of 52 and the blue at 55 . What is the index of refraction
for each color?
nred = ________
nblue = _______ What is the velocity of the blue light as it
passes through the prism.
vblue prism =...
