True or False: Light travels in curved paths.

• True

• False

In which scenario is the one-way mirror phenomenon most pronounced?

How does our ability to see an object depend on the interaction of light?

• Light must be absorbed by the object to be visible.

• Light must reflect off the object and enter our eyes.

• Light must refract through the object to be visible.

• Light must scatter in all directions from the object.

In a one-way mirror, which part of the glass allows some light to transmit through?

• The thick silver layer

• The paint layer

• Impurities and dust on the glass

• The gaps in the silver layer

Why does a one-way mirror appear reflective from one side and transparent from the other side?

• Due to the presence of impurities on the reflective side

• Because the glass is fully covered in silver on the reflective side

• Because there are gaps in the silver layer, creating microscale structural differences

• It's an optical illusion with no scientific explanation

What role does the paint layer play in the functioning of a one-way mirror?

• It enhances transparency on both sides.

• It adds color to the mirror.

• It contributes to the reflection on both sides.

• It helps reduce impurities on the glass.

Why is understanding the microscale structure of a material important in explaining how one-way mirrors work?

• It determines the color of the mirror.

• It can cause variations in how the material interacts with light.

• It affects the thickness of the glass.

• It determines the quality of the reflection on the mirror.

Which two statements best describe what happens to the light after it shines on the teacher?

• Some of the light that reflects off the teacher transmits back through the one-way mirror to the student’s eyes.

• Some of the light that reflects off of the teacher is destroyed.

• Some of the light that reflects off the teacher travels back to the teacher’s eyes.

• Some of the light reflects off the teacher transforms into sound waves.

• the shiny, silver parts

• the strong frame

• the opening at the top
