13 Questions
Name three properties of light that can be studied in a physics lab.
Intensity, direction, frequency (color) and polarization.
What is the definition of a property?
An attribute, quality or description of something, usually in a way that can be quantified or compared.
What are the fundamental properties of light?
Intensity (brightness), direction, frequency (color) and polarization.
What is the purpose of investigating the properties of light in different circumstances?
To understand how light behaves.
What are the steps in the lab experiment described in the text?
Step 1: Fold the paper, draw a line along the fold. Step 2: Stand the mirror upright on the line. Step 3: Draw a dot or cross on the paper and stick a pin or thumbtack in it.
What is the purpose of using a ruler in step 5 of the lab?
To draw a line from your eye, along the paper, to where the pin appears in the mirror.
What should you do after step 6 of the lab?
Extend the two lines until they cross using the ruler.
What should you do with the lines on the side of the mirror where the pin was in step 7?
Keep the lines solid.
What should you do with the lines on the opposite side of the mirror in step 7?
Dash the lines.
What should you do where the lines meet the mirror in step 8?
Connect them to the dot or cross you drew.
What should you do where the line bounces off the mirror in step 9?
Draw a line at 90 degrees (right angles) to the mirror surface.
What does the laser pointer demonstrate in step 9?
That light travels in straight lines and bounces off the mirror.
Which property of light does the fact that the laser pointer is red demonstrate?
Frequency or color.
