PLEASE I NEED THUS THX SOOOOOO MUCH IT MEANS A LOT! THIS WILL KILL MY GRADE IF ITS BAD Properties of Light Lab Report Instructio

ns: In the Properties of Light—Bending Light Lab you will explore how light rays interact as they pass from one material, or medium, to another. Record your observations in the lab report below. You will submit your completed report. Name and Title: Include your name, instructor's name, date, and name of lab. Objective(s): In your own words, what was the purpose of this lab? 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. Procedure: Please be sure to identify the test variable (independent variable) and the outcome variable (dependent variable) for this investigation.

Answer:

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.

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

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.

Projectiles that strike objects are good examples of inelastic collisions. A 0.1 kg nail driven by a gas powered nail driver col
Ratling [72]
In an inelastic collision, only momentum is conserved, while energy is not conserved.

1) Velocity of the nail and the block after the collision
This can be found by using the total momentum after the collisions:
p_f=(m+M)v_f=4.8 kg m/s
where
m=0.1 kg is the mass of the nail
M=10 kg is the mass of the block of wood
Rearranging the formula, we find v_f, the velocity of the nail and the block after the collision:
v_f= \frac{p_f}{m+M}= \frac{4.8 kg m/s}{0.1 kg+10 kg}=  0.48 m/s

2) The velocity of the nail before the collision can be found by using the conservation of momentum. In fact, the total momentum before the collision is given only by the nail (since the block is at rest), and it must be equal to the total momentum after the collision:
p_i = mv_i = p_f
Rearranging the formula, we can find v_i, the velocity of the nail before the collision:
v_i =  \frac{p_f}{m}= \frac{4.8 kg m/s}{0.1 kg}=48 m/s

A mass hanging from a spring oscillates with a period of 0.35 s. Suppose the mass and spring are swung in a horizontal circle, w
Annette [7]

Answer:

66 rpm

Explanation:

The period of oscillation is given by

T=2\pi \sqrt{\frac {m}{k}}

\frac {k}{m}=\frac {4\pi^{2}}{T^{2}} where  T is time period of oscillation which is given as 0.35 s, k s spring constant and m is the mass of the object attached to the spring.

Also, net force is given by

Net force=m\omega^{2} L

\omega=\sqrt{\frac {k\triangle L}{mL}} where \triangle L is the elongation, L is original length, \omega is the angular velocity

Substituting the equation of \frac {k}{m} into the above we obtain

\omega=\sqrt {\frac {4\pi^{2}\triangle L}{T^{2} L}}

\omega=\sqrt {4\pi^{2}\times 0.15L}{0.35^{2}\times L}}=6.952763\approx 6.95 rad/s

6.95\times\frac {60 s}{2\pi rad}\approx 66 rpm

Jose has a solid green ball. Which color(s) of light does this ball reflect?
lorasvet [3.4K]
If the ball is green, then it is absorbing all the colors of light except green. This means that it is reflecting or denying the absorption of green light, that is why the ball is green. Therefore, your answer would be B.

Hope I helped :)

About 85% sure on this one.

PLZZZ HELP
Doss [256]

Answer/Explanation:

The weight of an object is defined as the force that is exerted due to the gravitational force.

Mathematically, it can be written as :

W = m g

Where

m is the mass of the object

g is the acceleration due to gravity

Also,  

We know that the value of g varies with respect to the location. At the equator, the value of g is less as compared to the poles.

The feature of an object that affects its weight are :

Mass of the object

Location of the object

How much force Earth exerts on the object

Using Newton’s second law, why do you think a cotton ball may not be used as a baseball in a baseball game.
stich3 [128]
