Which best explains why the teacher sees the student? (Note: these are all true, but which one is the answer to this particular question)
Light bounces off the teacher and transmits through the glass back to the student's eyes.
The eye sees things upside down and our brain turns the image right side up.
There is a light on in the room where the student is standing and it is dark where the teacher is standing. This stronger light is reflected off of the mirror back to the student's eyes.
There is a light on in the room where the student is standing and it is dark where the teacher is standing. The stronger light is bouncing off of the student, through the one-way mirror, and back to the teacher's eyes.
Why is it hard to see your phone or tablet screen in bright sunlight even though it is on?
the light reflecting from the sun is so bright it is hard to detect the device's light
the light from the device is so much brighter but you are squinting because the sun and therefore cannot see the screen.
The device is on battery save mode and dims because of the sun's power
all of these
Which REFLECTS the MOST light?
one way mirror
glass
these are all the same amount of reflection
Which of these would you expect to TRANSMIT the most light?
mirror
one way mirror
glass
they all transmit the same amount of light
What things are important with the mirror phenomenon in the video we saw in class with the student and teacher.

What is happening between light and an object so that we an see the object?

Light is reflecting off the object into our eyes.
Light is being transferred through the object.
Light is reflecting off our eyes.
You can see objects outside of a window because light _____________ through the glass.
scatters
reflects
transmits
absorbs
Which part of the eye refracts the light onto the retina?he glass.
pupil
cornea
iris
lens
Why does the brain pay more attention to the light from the music student?

the light reflected from the student is a weaker input
the light from the student is faster
the light reflected from the student is a stronger input
Light passing through a lens and bending is an example of ____________
reflection
refraction
transmission
absorption

types
lines

the strongest signal
the weakest signal
all the signals equally
none of the signals
Which is true?
