Waves and Light
What does Sound travel the fastest through?
What does light travel through the fastest?
Solid
Space
Looking in a mirror is an example of what?
Reflection
The highest point of a wave.
Crest
A material that allows light to pass through it.
Transparent
The complete range of electromagnetic waves placed in order of increasing frequency
EM SPECTRUM
Does light change speeds while going through objects?
YES
Why does a pencil looks bent in water?
Refraction
The distance from the midline of a wave to the crest or trough.
Amplitude
A material that scatters or absorbs some of the light and allows some of the light to pass through it.
Translucent
The energy transferred through space by electromagnetic waves
EM RADIATION
What is the difference between visible light and nonvisible light. (why cant we see nonvisible light?)
They have different wavelengths
The deeper down you go in the ocean it appears green and blue why?
Absorption
How many times a wave goes through a certain point.
Frequency.
Which wave does not need a medium to travel?
Light
Transferring of energy to the material it hits.
Absorption
What is a wavelength?
The length between the crest of one wave and the crest of another.
Why does a green shirt look green?
The green is being reflected and all other colors are being absorbed
The measurement from crest to crest or trough to trough.
Wavelength
How fast a wave travels through a medium depends on the mediums......
Density
Matter that a wave travels through.
Medium
The order of the colors of the rainbow. Start with lowest frequency to highest frequency.
Red, orange, yellow, Green, Blue, Indigo, Violet
How does a rainbow form?
Refraction of sunlight through water molecules in the sky.
If a wave has a long wavelength then it has.....
Low Frequency
Low Energy
A material that does not allow light to pass through, light is either, reflected or absorbed.
Opaque
Electromagnetic wavelengths immediately outside the violet end of the visible spectrum.
ULTRAVIOLET
