Sound Waves
Yes!
Can light travel through space? Why?
Yes. It does not require a medium
Transverse waves go which direction?
Up & down
Longitudinal waves go which direction?
Back & forth (left to right)
What is the EM spectrum?
The range of all types of EM radiation and their wavelengths.
What kind of waves are sound waves? (That move back & forth)
Longitudinal
What does it mean when light transmits?
Light goes through
Transverse waves can be which two types of waves?
Mechanical or electromagnetic
Do longitudinal waves require a medium to travel through?
Yesss
How many regions are in the EM spectrum?
7 regions
Amplitude determines what?
How loud the sound is.
What is a refraction?
Light bends when passing through medium
Do transverse waves require a medium?
Not always. Mechanical waves do, electromagnetic waves do not.
Longitudinal waves are also known as what?
Compression waves
Does the EM spectrum go from increasing or decreasing wavelength?
increasing or decreasing frequency?
decreasing wavelength
increasing frequency
If the sound wave has a high frequency, what will the pitch be?
high pitch
What is reflection?
Light bounces off shiny surfaces: mirror, foil, metal
Do transverse waves move parallel or perpendicular?
Do longitudinal waves move parallel or perpendicular?
Parallel
What does ROYGBIV stand for?
Red, orange, yellow, green, blue, indigo, violet
An object vibrating slow will have what kind of pitch and frequency?
Low pitch, low frequency
What is absorption?
Light goes into and stops
Light waves are transverse, and also what type of waves?
Electromagnetic
Sound waves are an example of longitudinal and what kind of waves?
Mechanical
