Types of waves
What type of wave does not require a medium through which to travel
Electromagnetic wave
Define Medium
Material through which a mechanical wave moves
what is the number of waves that pass a point in one second
Frequency
What occurs when a wave bounces of a material
Reflection
Sound is a form of what
Energy that results when vibrating materials produce longitudinal waves that travel through a medium
What type of wave causes parallel motion of the medium through which it travels
Longitudinal wave
Define Crest
Highest point on a wave
How do you measure wave frequency
In hertz
What happens when a wave is reflected
It flips upside down
Sound travels through air at a speed of
342 meters per second
What type of wave causes perpendicular motion of the medium through which it travels ( in relation to the wave)
Transverse wave
Define Trough
Lowest point on a wave
How is wave speed calculated
Wavelength x frequency
What does reflection not change
The speed or frequency of a wave
Intensity is measured in a unit called the
Decibel
What type of wave transmit energy through a medium
Mechanical wave
Define Wavelength
Distance from a point on a wave to the same point on the next wave
What is related to the amount of energy carried by a wave
Amplitude
All types of waves can be
Reflected
Frequency determines the
Pitch of sound
What type of wave travels fastest in solids and slowest in gases?
Sound waves
Define Frequency
Number of ways that pass a point in one second, measured in hertz
The greater the amplitude the more
Energy it carries
Waves move at different
Speeds through different materials
Humans can hear frequencies between
20-20,000 hertz
