Vocab
happens when a wave bounces back to the source
Reflection
when 2 waves meet along a medium and the displacement is going in the opposite directions
Destructive interference
Define medium
what the waves is traveling trough. Mediums can be a vacuum, solid, liquid or gas.
True or false
Water cannot be a medium for light to travel through
False
What are the colors of the rainbow?
Red Orange Yellow Green Blue
Indigo Violet
happens when a wave changes direction to go around an object or through an opening
Diffraction
happens when a wave is bent as it passes through a new medium
Refraction
If you mix red and yellow paint what color will be reflected?
Orange
How can two radio stations sending signals out into the same space at the same time?
If they have the have different frequencies, then they can occupy the same space at the same time without interfering each other.
3 things light waves can do
Transmit
Absorb
Reflect
a substance that can transmit energy, such as light, heat, or sound waves, from one place to another examples solid like the ground, liquid like water and gas like air
Medium
a tiny particle or bundle of electromagnetic radiation
Photon
True or False
Light with a higher frequency will be reflected less when traveling through a prism.
False
What is the difference between reflection and refraction?
Reflection is bouncing a wave back to the source.
Refraction is the bending of a wave but not back to the source.
Black objects absorb or reflect light
Absorb
when 2 waves meet along a medium and the displacement is going in the same direction
Constructive interference
happens when a light wave goes into the object and does not bounce off
Absorption
Why is a rainbow different colors?
Light is being refracted through water in the atmospere
Define Interference
Interference occurs wen crossing wave patterns result in a loss of energy for some waves and an increase of energy for other waves.
White objects absorb or reflect light
Reflect
an object that does not allow light to pass through it
Opaque
a material allows light to pass through it without scattering, and objects on the other side of the material are clearly visible
Transparent
True or False
A white object reflects wave lengths of light.
True
What are the the two types of Interference?
Constructive and Destructive
What is Mrs. W favorite color?
Purple
