|
A _______________________ is a repeating disturbance or movement that transfers energy through matter or space. |
Wave |
|
|
Waves that can only travel through matter are called ________________________. |
Mechanical Waves |
|
|
The matter the waves travel through is called the __________________________. |
medium |
|
|
A ____________________ that waves travel though can be a solid, liquid, gas, or a combination of these.
|
medium |
|
|
In this type of wave matter in the medium moves back and forth at right angles to the direction that the wave travels. |
transverse wave |
|
|
In this type of wave matter moves back and forth in the same direction that the wave travels. |
Compressional/Longitudinal |
|
|
During an earthquake the earth's crust vibrates creating ______________________ waves that carry energy outward. |
seismic |
|
|
The high points on a transverse wave are called? |
crests |
|
|
the low points on a transverse wave are called? |
troughs |
|
|
The distance between a point on a wave to another point just like it is referred to as the ________________________. |
Wavelength |
|
|
The region on a longitudinal wave where coils are close together/dense is referred to as the _______________ region. |
compression |
|
|
The region on a longitudinal wave where coils are farther apart/less dense is referred to as the ______________ region. |
rarefaction |
|
|
The ________________________ of a wave is the number of wavelengths that pass a fixed point each second. |
frequency |
|
|
Frquency is express in what unit? |
Hertz (Hz) |
|
|
What is the formula for wave speed? |
wave speed = wavelength x frequency |
|
|
The measure of the amount of energy a wave carries is called the wave's ___________________. |
amplitude |
|
|
The greater the amplitude, the greater the __________________. |
energy |
|
|
____________________ occurs when a wave strikes an object and bounces off of it. |
reflection |
|
|
In _____________________ reflection, the reflection provides a mirror image. |
regular |
|
|
___________________________ is the bending of a wave caused by a change in its speed as it moves from one medium to another. |
refraction |
|
|
___________________________ occurs when an object causes a wave to change direction and bend around it. |
diffraction |
|
|
When two or more waves overlap and combine to form a new wave, the process is called __________________. |
interference |
|
|
The transfer of the energy of a wave to matter as the wave passes through it is called _______________________________.
|
wave absorption |
|
|
_____________________________ takes place when two or more waves arrive at the same point, then superimpose themselves on one another. |
wave superposition |
|
|
__________________________________ are made by vibrating electric charges and can travel through space where matter is not present. |
Electromagnetic waves |
|
|
The energy carried by electromagnetic waves is called __________________________. |
radiant energy |
|
|
All electromagnetic waves travel at ____________________ in the vacuum of space. |
300,000 km/s |
|
|
Because light is an electromagnetic wave, the speed of electromagnetic waves in space is usually called __________________________. |
The speed of light. |
|
|
The entire range of electromagnetic wave frequencies is known as the ______________________________. |
electromagnetic spectrum |
|
|
Electromagnetic waves are described by different names depending on their __________________________ and __________________________. |
Frequency and wavelength |
