Molecules

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

The wavelength decreases.

The wavelength turns into amplitude.

The wavelength increases.

Light travels faster than sound.

True

False

Which type of wave requires a medium, such as water or air, to transfer energy through molecular collisions?

Mechanical waves

Transverse light waves

Electromagnetic waves

Radio waves

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

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

Loud rooms reflect sound, where quite rooms absorb them.

Sound waves are not affected by the materials a room is made with.

Loud rooms refract sound, where quite rooms reflect it.

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

The light wave has a long wavelength

The light wave has a high amount of energy

The light wave has a high brightness.

The light wave traveling very fast

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

The sound wave has a long wavelength

The sound wave has a high amount of energy

The sound wave wave traveling very fast

The sound wave has a high pitch.

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

At a random angle determined by the mirror's density.

At the same angle at which it hits the mirror.

Straight up at 90 degrees no matter what.

At half the angle of the incident ray.

Question 13

13.

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

Vacuum (Space)

Question 15

15.

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?

Infrared light 

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.

Radio waves are low energy waves that are not harmful.

Choose the claim that is accurate about light:

Light waves and sound waves both require a medium to travel and carry their respective energis.

All visible light travels at the same speed through different types of mediums (solid, liquid, or gas).

Light travels from the Sun to Earth by compression and rarefraction through the medium of space. 

Changing the frequency of visible light changes the color of the light.

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

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

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

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

It reflects red and yellow wavelengths which allows white light wavelengths to be transmitted.

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 not reflected, refracted, the light is absorbed. We feel this absorption as _________________________. 

electrical energy

thermal energy

kinetic energy

potential 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 

To create the prism phenomena below, a light ray travels through the air (less dense) and then into the prism (more dense). 

What happens to the speed and path of the light ray? Choose the THREE correct statements.

The path of light bends.

Light reflects.

The path of light stays the same (straight).

Light refracts.

The speed increases.

The speed slows down.

The archer fish is a tropical fish that can hunt for its prey from below the water. It catches its food by spitting water on its land-based prey. The archer fish has evolved to be able to overcome what issue when it comes to hunting in the water with catching its prey on land?

Reflection of light

Transmission of light

Absorption of light

Refraction of light

Categorize the different descriptions of Sound and Light.

Decreases speed with higher density

Needs a medium

Increases speed with higher density

Does not need a medium

Sound 

Light

Question 28

28.

Question 29

29.

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.

They are inversely related, higher frequency means lower energy.

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

Brain

Retina

Optic Nerve

Pupil

Cornea

Lens

Question 35

35.

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

cornea

rods

cones

pupil

Match the structure of the eye with its correct function.

Lens

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

Iris

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

Retina

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?

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

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

The spectrum of colors is refracted by the object so that it appears blue to our eyes.

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

Question 39

39.

Why can we see the color of a red apple?

The apple refracts white light into a red beam.

The apple creates its own red color through nuclear fusion.

The apple absorbs red wavelengths and reflects all other wavelengths.

The apple reflects red wavelengths and absorbs all other wavelengths.

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

The water acts as an opaque object that blocks light.

The light reflects off the surface of the water.

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

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

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

The white light is filtered into individual particles.

The prism reflects each color.
