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

Biology

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.

Some species that appear to be very different from other species can actually have similar anatomy. For example the scientist be

Following are some examples of homologous structures.
A dolphin's flipper, bird's wing, cat's leg, and the human arm are considered homologous structures. Whereas human beings have bones such as the humerus, ulna, radius, wrist bones, and fingers, these features appear as similar bones in form in the other animals. Bats, whales, and many other animals have very similar homologous structures, demonstrating that these creatures all had a common ancestor.
The tailbone in human beings is so-named because it is a homologous structure to the beginning of many animals' tails, such as monkeys. It is known as "vestigial" because it is the last vestige of what was once a tail.
All mollusks have a "foot" that they use to travel. This foot is homologous although it may not appear to be immediately - close inspection demonstrates that in terms of form and function, gastropods, cephalopods, and bivalves share this homologous structure in common.
Mammals share the homologous structure of the vertebrae in common. For instance, in spite of its height, the giraffe has the very same number of neck bones (seven) as a giant whale and a tiny human being.
Human beings, dogs, and cats all have similar pelvises, which are homologous structures to a vestigial pair of bones that snakes have. These bones are the last remains of a pelvis, with no legs to attach.
Our eyes are homologous to the eye bulbs which blind creatures who live in caves have on their heads.
All organisms contain homologous plasma membranes with what is called a phospholipid bi-layer.
The wrist bone of the human being is homologous with the structures of many other animals, including the dolphin and the bird. A homologous structure in the panda looks like a sixth appendage, but it is actually a modified wrist bone that helps the panda bears pick leaves off the trees more dexterously.
An auditory bone that exists inside the ear of mammals is a homologous structure to the reptile's jaw bone (including the dinosaurs) as well as the jawbone of species of fish that are still in existence today.
The carpals, metacarpals, and phalanges of the human hand have homologous structures in a variety of animals, and they're not all mammals. For instance, these features are seen in penguins and reptiles as well as the mammals to which human beings are more closely related.
The genetic code among all living things is homologous - extremely similar although other genetic codes exist. This suggests a common ancestor.
Wasps and bees have stingers that they can use when they feel they are in danger. However, this is a homologous structure to the ovipositor of other organisms - the feature that allows these organisms to lay eggs.

Vika [28.1K]

Answer: Organism in this domain can be defined as living things that has an organized structure, and responds to stimuli, and has ability to reproduce, grow, and maintain a state of equilibrium. Organisms are of two types which are unicellular and multi cellular organisms.

Explanation: unicellular organisms are organisms that are made up of only one cell which carries out all the functions needed by the oragnism. Multicellular organisms are organisms that are made up of more than one cell. These organisms uses many different cells to function.

Unicellular organisms are often found in extreme environments such as hot springs, polar ice and frozen tundra.

Unicellular organisms have cell that contain a nucleus.
