Waves Basics
The distance from one crest to another, or from one trough to another.
Wavelength
Units that means one cycle/sec
Hertz
They can allow us to see
The highest point of a wave-
Crest
Example of a vacuum:
Outer Space
The number of occurrences of a repeating event per unit of time.
Frequency
A wave with large amplitude carries more _________ than a wave with small amplitude
Enegry
When two waves meet is known as what?
Interference
What is a medium?
The substance that carries a wave from one location to another.
Can sound travel through space?
NO.
A measure of the displacement of the wave from its rest position.
Amplitude
What is a wave that doesn't require a medium?
Electromagnetic waves
Longitudinal
The time needed for one full wave cycle to complete
Period
Waves that require a medium-
Mechanical
What is the source of all wave motion?
Vibrations
What are the 4 characteristics of a wave?
Amplitude, Frequency, Wavelength and Period
Which type of waves are fastest?
Light Waves
The bouncing back of a wave as it meets a surface or boundary
Reflection
What is the reason a pencil appears different under water?
Refraction
The state of a body at rest or in uniform motion, the resultant of all forces on which is zero.
Equilibrium position
What is the relationship between wavelength and frequency?
The shorter the wavelength, the higher the frequency.
In which does sound travel fastest?
Solids
What are the 4 characteristics of a wave?
Amplitude, Frequency, Wavelength and Period
How do particles in a transverse wave vibrate?
Perpendicular to the direction of the wave
