Waves Basics
This is a disturbance that transfers energy through matter or space
Wave
When a wave bounces off a surface
reflection
What is the equation to calculate wave speed?
v = λf
These waves have the longest wavelength and lowest energy.
Radio Waves
The matter a wave travels through.
Medium
Waves that require a medium to travel through
Mechanical Waves
When a wave bends due to a change in speed between mediums.
Refraction
If frequency increases, wavelength will do this.
Decrease
The only electromagnetic waves visible to the human eye (specifically from the EMS)
Visible Light
Sound travels fastest in this state of matter.
Solids
Type of wave, that particle motion is perpendicular to wave motion.
Transverse Wave
When waves bend around an obstacle or opening.
Diffraction
A wave travels at 72.26 m/s with a wavelength of 8.1 m. Find frequency.
8.92 Hz
These waves are used to take images of bone.
X-Rays
Increasing amplitude makes a sound wave do this.
Become louder
The distance from crest to crest or compression to compression
Wavelength
When two waves combine to form a new wave.
Interference (Constructive/Destructive)
A wave has a frequency of 7.26 Hz. What is the period?
0.14 seconds
These waves from the sun help your body produce vitamin D.
UV rays
This relationship describes how pitch changes as a source moves
Doppler Effect
This property represents the energy of a wave and determines loudness in sound.
Amplitude
This occurs when an object vibrates at its natural frequency due to another vibrating object.
Resonance
Ocean waves move at 3.5 m/s with wavelength averages of 4.0 m. What is the frequency of these waves?
0.88 Hz
All electromagnetic waves share this property in a vacuum.
Same speed. 3.0x108 m/s
If the angle of reflection is 25°, what is the angle of incidence?
25°
