Light from the teacher is a stronger signal.
Light from the teacher is a weaker signal.
Light from the teacher has no effect on what the student sees.
Light from the outside has no effect on what the student sees.
How is a one-way mirror made differently than a regular mirror?
A one-way mirror is made by applying a thin layer of film that is “half-silvered” over glass.
A one-way mirror is made by creating holes in the glass.
A one-way mirror is made by coating the glass on one side in silver and paint.
A one-way mirror is not made differently. The secret is in the lighting.
In order to see any object, what has to happen?
Light has to shine on the object first and then reflect into the eyes.
Light has to shine into the eyes and then onto the object.
The path that light travels does not matter.
None of the above

Reflection is the throwing back by a body or surface of light, heat, or sound without absorbing it.
True

What is thermal energy?
Thermal energy refers to the energy contained within a system that is responsible for helping others.
Thermal energy refers to the energy contained within a system that is responsible for its temperature.
Thermal energy refers to the energy contained within a system that is responsible for growing things quickly.
Thermal energy refers to the energy contained within a system that is responsible for being a solid.
Lasers produce a beam of light that can be focused on a small area. A teacher uses two mirrors to shine a laser beam onto a box. Which diagram shows how the teacher should position the two mirrors?
(a)
Click on the correct letter for the correct angle of reflection?
Reflection is when light rays (a)
Light rays bounce off a surface (a)
Light bounces off when it is:
(a)
When light hits an object, the rays can pass through it, bounce off it, or be absorbed by it. Light rays that bounce back are (a)
Which is light bouncing off of a surface? (a)
A light ray hits the surface of an object and bounces back away from the surface. This is an example of (a)
The ray of light that strikes the surface is known as the (a) . The reflected light corresponding to a given incident ray is called (b) .
What is happening in this picture?
Reflection
Refraction
(bounces)
Light travels through an object during
absorption
reflection
transmission
diffraction
What is the purpose of the silver layer behind the glass on a regular mirror?
to allow light to pass through and refract
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...
some light to be reflect and some light to be transmitted
some light to be refracted and some light to be absorbed
all light to be reflected
all light to be transmitted
What role do sensory receptors in the eyes play when looking at a one-way mirror from the reflective side?
They detect the mirror’s reflective surface
They sense the people on the other side
They change the mirror’s properties
They create a mirror image in the brain
When light hits a one-way mirror, what happens?
It is only absorbed
It is only transmitted
It is reflected on one side and transmitted through the other
It completely disappears
Why can’t we see through a one-way mirror when standing on the reflective side?
Because the light is too bright
Due to the absence of light on the other side
Because the sensory receptors in our eyes can’t process it
The mirror’s coating prevents vision from that side
When light passes through a one-way mirror, what do the sensory receptors in our eyes detect?
The light coming from the other side
Only the reflected light
The mirror itself
The absence of light
In the context of vision, how is looking through a one-way mirror different from a regular window?
The brain processes the images differently
One-way mirror images are always upside down
A one-way mirror only shows moving objects
A one-way mirror controls light transmission and reflection
What happens in our eyes that is similar to seeing through the transparent side of a one-way mirror?
The pupil dilates completely
Light passes through and allows us to see
The eye reflects all incoming light
The eye changes color based on light
How does the path of light through a one-way mirror differ from its path through a regular mirror?
It bends more in a one-way mirror
It is absorbed completely by a one-way mirror
It passes through one side of a one-way mirror but reflects off a regular mirror
It splits into colors in a one-way mirror
How does the brain interpret the path of light when looking at a one-way mirror?
It perceives the light as coming from multiple directions
It interprets the light as if it were a regular mirror
It gets confused and reverses the image
It adjusts based on the intensity of light
What happens to light when it shines on an object with a shiny, metallic surface?
It is mostly absorbed
It is mostly transmitted
It is mostly reflected
It changes color
In a one-way mirror, which side reflects more light?
The transparent side
The side that looks like a regular mirror
Both sides reflect light equally
Neither side reflects light

Clear glass
Colored glass
Metal sheet
What happens to light waves when they hit a frosted glass window?
They are focused into a beam
They are diffused
They become polarized
They are amplified
Why do different sense receptors trigger different types of responses in the brain?
Because all receptors respond to electromagnetic signals
Because different receptors are sensitive to specific types of stimuli
Because the brain processes all sensory inputs similarly
Because receptors transform all signals into chemical signals
What phenomenon occurs when light passes through a prism?
Reflection
Refraction
Absorbtion
Diffusion
How is light modified when passing through tinted glass compared to clear glass?
Tinted glass absorbs more light
Tinted glass reflects all light

How does light behave when it encounters a surface with a high index of refraction?
It bends away from the normal
It travels straight without bending
It bends towards the normal
It stops completely
What does the brain do when light signals are received from the eyes?
It immediately sends the signals to the arms
It processes them to form visual images
It stores them as sound memories
