What is the measure of how high or low a wave sounds?
Pitch
The distance between waves in a wavelength is called what?
wavelength
The highest point of a transverse wave is called what?
crest
Would an explosion in space make any sound?
no, because space is a vacuum. there is no matter.
How does light travel?
In waves
True or false?
Sound is a mechanical wave.
True
Waves oscillate in different speeds. The number of oscillations produced is called what?
Frequency
The lowest point of a transverse wave is the what?
tough
When light hits something, like glass, on an angle, what happens?
It slows the speed and causes the light to bend.
What medium does light need to travel through
empty space
What is amplitude?
The distance a wave goes back and forth
When waves have a greater frequency, they will have more what?
Energy
The greater the amplitude ....
the louder the sound
What is it called when light hits a clear, curved piece of glass?
refraction
What is the bending of a light wave as it passes from one medium into a different medium?
Refraction
When is sound produced?
vibrations
When electromagnetic waves oscillate in a similar way, perpendicular to the direction the wave is traveling, what do we call these waves?
transverse
What is frequency?
Is the number of waves produced in any given time.
Why do black things and dark colors get hot under the sun?
it absorbs every color of light.
What is the time it takes for a wave to complete one cycle?
period
Sound travels faster though what?
liquids
which is faster, light or sound?
light
What kind of waves does a remote use?
What things do we humans use that involve refraction?
glasses, contacts, microscopes, or telescopes
