Unit 7 Lab Review
Speed of Sound Lab
1. You have a tuning fork with a frequency of
1000 Hz. Your pvc pipe has a diameter of 1
cm. You find that the tube resonates when
the top of the tube is 8.2 cm above the top of
the water. Using this information what is the
speed of sound?
2. In this lab what factor did we have to use to
find the theoretical value for the speed of
sound?
Speed of Sound Lab
Refraction/Reflection
1. What does the law of reflection state?
2. What is refraction?
3. How was the arrow formed by the light rays
passing through the lens different from the
actual arrow?
Refraction/Reflection
1. The angle of incidence is equal to the angle
of reflection
2. The bending of a wave as it goes from one
medium to another
3. It was inverted (upside down)
Stations Lab
1. What is the optical device in which the
refracted image is larger?
2. What is the optical device in which the
reflected image is larger?
3. A
lens causes light rays to converge.
4. Draw what happens to the light rays when
five beams of light (such as those from a
ray box) hit a concave lens.
5. If you walk into a bank or store and see
your image and you’re all tiny and
disfigured, what type of optical device are
you peering into?
6. Name the optical device that causes reflected
light rays to converge.
7. Describe the image of an object far away
when viewed through a convex lens.
8. In the index of refraction lab which test tube
was hardest to see? Why?
9. How did the size of the slits affect the
pattern created by the laser shining through
the diffraction plate?
1. Convex lens
2. Concave mirror
3. Convex
5. Convex mirror
6. Concave mirror
7. Inverted
8. Oil in oil. The index of refraction of the material
inside the test tube was the same as the material in
the beaker.
9. Smaller slits = more space between dots
