Eye see you
True or False: The teacher sees the student, but the student does not see the teacher because the teacher's room is darker, so less light reflects back to the student.
True
How much light does a one-way mirror reflect?
50%
How does Pete (the student) see himself?
Light hits Pete, then the mirror, then Pete's eyes
When you touch a stove top and burn your hand, how is the thermal energy transferred to your hand?
conduction (heat energy transferred through touching)
What is it called when light bounces off of a surface
Reflection
Which light was off in the room teacher or student?
Teacher
If we use a regular mirror instead of a One-way Mirror the teacher would still see the student.
No
What is it called when light APPEARS to bend through a transparent material/
Refraction
True or false: light waves behave similarly to sound waves
True!
What is it called when light or sound passes through
transmit
Name at least two parts of the eye
retina, optic nerve, iris, pupil, etc.
If a student shines a flashlight on a piece of paper, what will the paper do?
a. reflect light
b. scatter light
c. transmit light
scatter (and absorb some) light
Optic Nerve
True or False: Objects that are black absorb more light energy compared to objects that are white.
True
What is an independent variable
The thing that we change in an experiment
Was any light that was reflecting off the teacher actually transmit through the one-way Mirror & reach the student's eyes?
Yes
What's is a mirror?
a reflective surface, usually made of glass coated with a metal amalgam like silver, that reflects a clear image.
What part of the eye is used to take in light?
Pupil
Why is it better to compare averages when analyzing class lab data?
It's easier to process and compare two numbers vs. 16+ numbers.
Also, it helps reduce the effects of random errors (aka anomalies) and increases reliability
Is a flashlight lens concave or convex?
Convex
Why could the student only see himself, and not the teacher? Use the following in your answer: reflecting, teacher, student, weak signal, strong signal, eyes brain
The light reflecting off the teacher was a weak signal entering the student's eye. The light reflecting off the mirror & entering the student's eyes made a much stronger signal, so the student's brain only focused on the strongest signal.
Name something you can see your reflection in that's not a mirror
Puddle, window, etc. (answers may vary)
Describe light scattering
Light scattering is the phenomenon where light changes from a straight path when it interacts with particles in an object. Example: light is scattered when it hits paper, and reflects in "scattered" directions.
Shiny surfaces ___________ more light, reducing energy absorption
reflect
What happens to light reflecting off of a rough surface?
It scatters
