Sound and light waves both transfer what as they move?

Energy

Matter

Mass

If the frequency of a light or sound wave increases, what happens to its wavelength?

The wavelength stays the same.

The wavelength increases,

The wavelength decreases.

Light travels faster than sound.

True

False

How can sound waves make a room 'loud' versus 'quiet' based on wave behavior?

Loud rooms refract sound, where quite rooms reflect it.

Loud rooms reflect sound, where quite rooms absorb them.

Loud rooms have low frequencies, where quite rooms have high frequencies,

If a light wave has a high amplitude, what does this specifically indicate about the wave?

The light wave has a high brightness.

The light wave has a high amount of energy

The light wave has a long wavelength

If a sound wave has a high amplitude, what does this specifically indicate about the wave?

The sound wave has a high amount of energy

The sound wave has a high pitch.

The sound wave has a long wavelength

When light strikes a smooth mirror, at what angle does the reflected ray bounce off?

Straight up at 90 degrees no matter what.

At half the angle of the incident ray.

At the same angle at which it hits the mirror.

Question 12

12.

Order the the objects through which LIGHT travels through FASTEST (top) to SLOWEST (bottom). 

Fresh Water (Liquid)

Steel Door (Solid)

Vacuum (Space)

Question 14

14.

Mr. Leon, Ms. Irwin & the Navy team were at the beach catching some sun. Mrs. Yates reminded everyone to put on their sunblock. What type of EMS wave does sunscreen protect against?

Ultraviolet light

Gamma rays

Microwaves

According to the NewsELA research article, what statement is NOT true about radio waves and phones?

Radio waves in phones heat up the brain and head enough to cause harm

Current studies suggest that phone radio waves do not hurt people.

Higher energy waves like x rays can cause harm.

If an object is white and shines brightly, what does that tell you about how much light it absorbs or reflects?

It reflects all the colors (wavelengths) on the visible light spectrum

It absorbs only the red and yellow part of the spectrum, allowing white light to reflect

It absorbs all of the colors (wavelengths) of the visible spectrum

When an object is clear, and we can see the images behind it, without any distortion, what is happening to the light?

Absorbed by the object

Reflected by the object

Transmitted by the object

If light is is absorbed, we typically feel this absorption as _________________________. 

electrical energy

thermal energy

kinetic energy

If you are designing an office space where you need privacy but still want light to come through the windows, what type of material would you use for the windows?

opaque

translucent

transparent 

Categorize the different descriptions of Sound and Light.

Increases speed with higher density

Decreases speed with higher density

Does not need a medium

Needs a medium

Sound 

Light

Question 24

24.

On the electromagnetic spectrum, how is frequency related to the energy of the wave?

Energy is only determined by amplitude in light waves, not frequency.

They are directly related, higher frequency means more energy.

Frequency has no effect on the energy of light waves.

Put the structures in the correct order starting with where light enters and travels to the brain.

Optic Nerve

Pupil

Retina

Lens

Cornea

Brain

Question 30

30.

A person with colorblindness is unable to see color the same as most people. Which part of the human eye is most likely damaged?

pupil

cones

rods

cornea

Match the structure of the eye with its correct function.

Iris

Layer at the back of the eye containing light-sensitive cells (rods and cones) that convert light into electrical signals.

Retina

Transmits electrical signals from the retina to the brain, where they are processed as images

Lens

Colored part of the eye that is a muscle. Controls the size of the pupil, adjusting light intake.

Optical Nerve

Transparent structure behind the pupil that focuses light onto the retina.

When an object appears blue to our eye what happens with the white light shining on the object?

Blue wavelengths of light are absorbed, the rest of the spectrum of visible light is being reflected.

All of the wavelengths of light are being absorbed and transmitted through the object.

Most of the wavelengths of light are being absorbed except blue which is primarily being reflected.

Question 34

34.

Why can we see the color of a red apple?

The apple refracts white light into a red beam.

The apple absorbs red wavelengths and reflects all other wavelengths.

The apple reflects red wavelengths and absorbs all other wavelengths.

Question 36

36.

Draw arrows to show the path of light when it hits the surface of the translucent glass.

You may draw up to 4 arrows

Question 37

37.

Draw arrows to show the path of light when it hits the surface of the transparent glass.

You may draw up to 4 arrows

Using the wave illustration, which letter represents the crest of the wave?

A

C

D

Using the wave illustration, which letter would you look at to measure the frequency of the wave?

A

B

C

D

What is the primary reason that when you look through a glass of water, a pencil would appear 'broken'?

The water absorbs the color of the light wavelength the straw reflects.

The water acts as an opaque object that blocks light.

The light changes speed and bends as it enters a new medium.

Why does a prism separate white light into a rainbow of colors?

Different wavelengths of light bend at different angles.

The prism absorbs all colors  except for the ones we see.

The prism reflects each color.

Use the Material and Refraction data table to answer the question. 

Which material has the highest index of refraction, meaning it bends light the most?

diamond

glass

water

What structure is letter C?

Cornea

Lens

Iris

Optic Nerve

What structure is letter D?

Lens

Iris

Cornea

In a dark room, the pupil will:

expand to let more light in

shrink to let more light in

expand to let less light in

shrink to let less light in
