(PLZ HELP, I CAN'T FAIL THIS, SO PLZ GIVE ME A GOOD ANSWER FOR THIS) Properties of Light Lab Report

Procedure:
Please be sure to identify the test variable (independent variable) and the outcome variable (dependent variable) for this investigation. Remember, the test variable is what is changing in this investigation. The outcome variable is what you are measuring in this investigation.

Test variable (independent variable):
Outcome variable (dependent variable):


Select Intro to begin.
Once the simulation loads, you will drag the protractor onto the screen so that the 0 lines up with the dotted line in the center of the screen.
You will test all three materials in the bottom, blue half of the screen: air, water, and glass.
Record your observations of how the light rays interact as they pass from air, on the top of the screen, through the three materials on the bottom of the screen

Data:

Record the data from each trial in the data chart below. Be sure to fill in the chart completely.

Material Interactions
List any observations you made as the light rays passed from the air on the top of the screen to the selected material on the bottom of the screen. Evidence
Using the protractor, measure the angle as the light passes from the top material to the bottom material on the screen. Also, note the index of refraction for each as indicated on the screen.
Trial One Air on top


Angle:

Index of refraction:
Air on bottom


Trial Two Air on top


Angle:

Index of refraction:
Water on bottom


Trial Three Air on top


Angle:

Index of refraction:
Glass on bottom



Conclusion:

Your conclusion will include a summary of the lab results and an interpretation of the results. Please write in complete sentences.

Did your data support your hypothesis? Use evidence to explain.
Which material refracted the light rays the most: air, water, or glass?
Which material refracted the light rays the least: air, water, or glass?
How does density affect refraction?
Diamonds are a very dense material. Predict what would happen to the light ray if you projected it from air through a diamond.
Explain where you observe reflection, refraction, and absorption of light in your everyday activities.

Objective(s):

In your own words, what was the purpose of this lab?

To explain how different materials make light bend.  

Hypothesis:

In this section, please include the if/then statement you developed during your lab activity. This statement reflects your predicted outcome for the experiment.

If I project light rays through (choose one: air, water, glass), then they will refract, or bend, the most.

If I project light rays through glass, then they will refract the most.  

Procedure:

Please be sure to identify the test variable (independent variable) and the outcome variable (dependent variable) for this investigation. Remember, the test variable is what is changing in this investigation. The outcome variable is what you are measuring in this investigation.

Material

Interactions

List any observations you made as the light rays passed from the air on the top of the screen to the selected material on the bottom of the screen.

Evidence

Using the protractor, measure the angle as the light passes from the top material to the bottom material on the screen. Also, note the index of refraction for each as indicated on the screen.

Trial One

Air on top

The light goes straight through the air  

Angle:  

Acute  

Index of refraction:

1.00

Air on bottom

 

Trial Two

Air on top

The light bends in the water  

Angle:

Actute  

Index of refraction:

1.34  

Water on bottom

 

Trial Three

Air on top

The light almost goes straight down when it hits the glass  

Angle:

Acute  

Index of refraction:

1.60  

Glass on bottom

 

Conclusion:

Your conclusion will include a summary of the lab results and an interpretation of the results. Please write in complete sentences.

Did your data support your hypothesis? Use evidence to explain.

Yes it did, the glass index refraction (1.60) is higher than the other ones.

Which material refracted the light rays the most: air, water, or glass?

glass

Which material refracted the light rays the least: air, water, or glass?

air

How does density affect refraction?

It reflects light.

Diamonds are a very dense material. Predict what would happen to the light ray if you projected it from air through a diamond.

The light would reflect everywhere,

Explain where you observe reflection, refraction, and absorption of light in your everyday activities.

In mirrors and when light from a window hits a glass of water.
