Traveling Light
Can light travel through a vacuum?
Yes
Does it matter which way the mirror is facing for the light to travel certain directions?
The light will relect the direction that it is facing.
How do glasses lens help you see?
By bending incoming light rays so they focus precisely on the retina at the back of your eye.
Do all prisms have to be clear?
Light will not be shined through if it is not clear
What are some common colors for lasers?
Can light travel through an opaque object?
No
Can a mirror reflect heat?
Yes because radiant heat travels as infrared and visible light, both of which bounce off reflective metallic surfaces.
What is a lens?
A transparent object that refracts/bends light.
How does light travel through a square prisms?
The light goes through the prism because its clear, and it bonces off of the corners.
How do lasers travel from one object to another?
The laser reflects off of something shiny and it bounces off to another shiny object.
What is the term used for the bending of light?
Refracting
If a mirror is facing at a 45degree angle what angle will it reflect at? What is this call?
45 degrees. Angle of Refraction
DAILY DOULBE
Why are the eye dilated during an eye exam?
It allows the doctor to see through the len to the back of the eye.
What are the visiable colors of the rainbow
red, orange, yellow, green, blue, indigo, violet
Why are lasers more damaging to eyes more than normal lights?
They are tightly focused and concentrated into a single, narrow beam that does not spread out.
How does light travel through water?
The water makes the light bend and slow down.
How does a two way mirror work?
It works when a light is on, on one of the sides and the other side is off and it creates a mirror effect on the light side and it is see through on the dark side.
What is the retina's job?
It detects light and converts it into nerve signals.
If a prism is wet, will we still see through it the same? Why.
No, it will be distorted because the water will bend the light rays.
If you wanted to make a laser tag square, is it possible to make a perfect square? How
Position the mirrors at exactly right angles of refraction to the laser beam.
How does light travel?
In an electromagnetic straight wave line called a ray.
What makes the mirror reflective?
There is a thin layer of metal, the metallic layer on the back, and bounces straight back through the glass to your eyes.
How can a lens form an image?
Lenses bend light rays so they converge or diverge, creating an image.
Name uses for lasers.
Surgery, barcode scanners, cutting materials, or pointing devices
