Characteristics
What is the Highest point on a wave called?
The Crest
A materials that lets all light pass through
Transparent
As the frequency of a sound wave increases so does the _____________________.
pitch
How does light travel?
In a straight line
What do waves carry?
Energy
What is the lowest point on a wave called?
Trough
Light bounces off something
Reflects
Does a sound wave with a smaller amplitude have a louder or softer volume?
softer volume
What color is an object if it absorbs all the light that hits it?
Black
What is the materials through which mechanical waves must travel called?
A medium
What is the height of a wave called?
Amplitude
This means light passes through
Transmit
Sound waves move as longitudinal waves, which move in a __________________ pattern as energy moves through.
back and forth
If an object looks blue, what is happening?
All the colors are being absorbed, except blue. Blue is being reflected
How is the angle of incidence related to the angle of reflection?
They are the same
What is the distance from a point on one wave to the next; crest to crest or trough to trough?
Wavelength
A material that lets some light pass through
Translucent
How is sound created?
By molecules colliding (vibrating) together repeatedly
True or false: Light is electromagnetic waves that do NOT need a medium to travel through, therefore can travel through space.
True
What type of lense is curved outward and causes light the bend inward?
Convex
A wave in which energy moves in an up and down pattern.
Transverse
Light bends when it moves from one medium to another at an angle.
Refraction
Is sound electromagnetic or mechanical waves?
Mechanical - needs to travel through a medium; can't travel in space.
What determines the color of light?
Its wavelength
What do energy, light and sound all travel as?
Waves
