What happens to light when it reaches the calm lake surface?

It reflects clearly.

It scatters.

It diffuses.

What can be concluded about light and vision from the class investigations?

We see better in the dark with no light source inside.

Light conditions alter how we seee reflections and objects through glass.

Objects inside are always less visible than reflections.

What causes someone to be nearsighted?

The eye focusing light too far behind the retina

The lenses in glasses being too thick

The eye being longer than normal from front to back

Why does the iris change the size of the pupil?

To improve the eye's ability to see at night

To change the color of the eye

To control how much light enters the eye depending on brightness

What happends when light from Room A's light source shines directly on the one-way mirror toward the teacher?

The light goes through the mirror without any reflection.

Most of the light is reflected back, while some is absorbed or passes through to the teacher's side.

The light immediately dims and does not affect the mirror.

Based on the light inputs to their eyes, what would the music student expect to see?

The student only sees the teacher and not themselves.

The student primarily sees their own reflection and faintly the teacher's.

The student cannot see anything at all.

What is the main purpose of conducting an investigation on how light interacts with different materials such as a one-way mirror, glass, or a regular mirror?

To understand how light is reflected and transmitted by each material

To find out which material is the most expensive

To determine which material is the heaviest

Why is it necessary to keep the experimental conditions the same while testing each material?

To ensure that the results are solely due to the differences in materials

So that the materials do not have to be changed

To prevent the light meter from recalibrating

Why can't light transmit through a regular mirror?

Because the glass is too thick for light to pass through

Because the mirror is always placed in dark areas

Because the silver layer and paint make the mirror opaque

What does 'half-silvered' mean in the context of one-way mirrors?

The silver layer is thin, creating a blend of transparent and reflective surfaces.

The silver is only applied to the edges of the mirror.

The silver is mixed with another metal to reduce its reflectivity.

Which of the following things do you think are important to explaining the one-way mirror phenomenon in the video with Pete and the music teacher. Check all that apply

The material that the window/mirror is made of

The amount of light in the rooms

Whether there is carpet on the floors

True or false, light only travels in a bent pattern.

True

False

What path of light allows us to see the vehicle in the reflection?

The sun reflects off of the vehicle, then reflects off of the person into car window.

The sun reflects off of the vehicle, then reflects off of the glass into our eyes.

The sun shines into our eyes, on the vehicle, then onto the window.

What is the purpose of the silver layer and black backing behind the glass on a regular mirror?

to allow light to pass through and reflect

to block light from passing though so it all reflects

to block light from passing through so it refracts

The silver grid on the front of a one way mirror allows...

all light to be transmitted

all light to be reflected

some light to be reflect and some light to be transmitted

Why does the student see himself? (Write this response as a CER and it has to be at least 3 sentences)

Match the material with the amount of light reflected and transmitted in a "perfect" experiment where a beam of light is shining on the following materials.

Draggable item		Corresponding Item
Glass		half (50%) reflected, half (50%) transmitted
One-Way Mirror		100% reflected, 0 % transmitted
Regular Mirror		10% reflected, 90 % transmitted

The _______ receives inputs but it is the _______ that processes what we see and turn it into an image. 

Light that has reflected off the student enters both the student's and the adult's eyes allowing people to see the student.

True

False

Which model below accurately shows why someone sees himself in a one-way mirror when the light is on in his room only.

What is the BEST piece of evidence we have that the one-way mirror's material is the same on both sides?

Equal amounts of light reflected and transmitted through the one-way mirror.

When the light was switched to the other side, the mirror side became a window and the window's side became a mirror.

A regular mirror and a one-way mirror reflected and transmitted the same amount of light.

What happens when someone is farsighted?

They can't see any objects clearly, regardless of the distance.

They can see up-close objects clearly but can not see distant ones.

They can see distant objects clearly but struggle with up-close items.

What role does the retina play in vision?

It projects images directly to the brain without processing.

It turns light into electrical signals for the brain to process.

It changes the focus of the lense for near and far objects.

What happens to light when it passes through a magnifying glass?

It reverses direction and exists back towards the light source.

It changes color based on the magnifying glass material.

It converges or comes together at a point.

If someone was standing outside and saw their reflection in a store window, it must be _______ outside and _______ inside the store.

Why can two people see different things while looking at the same object?

Because the input level might be different for each person.  

Because they will always choose the red object.

Because they will always choose the dark object.
