PLEASE I HAVE TO GRADUATE I NEED HELP ON THESE


Prelab:
1. Suppose the rectangle below represents a flat plane mirror. Draw a straight line in the
middle of the mirror that is perpendicular to the surface. This is called the
NORMAL
2. On the figure above, draw a straight line on the left side that makes a 30 degree angle
with the normal. Use arrows to show it coming down from above and striking the
mirror.
This is called the Angle of Incidence
3. On the figure above, draw what you think is going to happen to the ray after
reflection.
4. What do you think the angle you just drew is called?
Angle of
5. Compared to the angle mentioned in #2, what can you say about the measured value
of the angle mentioned in #4?
6. Suppose the same rectangle is mounted vertically as shown. Draw a small 2 cm high
candle approximately 6 cm to the left of the mirror
7. On the diagram above, draw where you think the candle's image is going to be from
the point of view as if you were looking into the mirror
from the left.
