electromagnetic spectrum
Waves that hit the surface and bounces back away from the surface are called
reflection waves
The distance between two waves crests is a wave's
wavelength
Rocks formed from heating and cooling of the magma are called.
igneous rocks
radio waves have the longest wavelength and lowest
frequencies
All electromagnetic waves travel at the same speed in a vaccum, but they have different
wavelengths and frequencies
What are interferences in which waves combine to form a wave with a larger amplitude than either wave originally had is called
constructive interference
Describes how quickly a wave moves
speed
Rocks formed from with shells, dust, and other rocks are called
sedimentary rocks
gamma waves have the shortest wavelengths and the
highest frequencies
radio waves carry information from
antenna to antenna
Points of maximum amplitude on a standing wave are called
antinodes
Describes the wave's energy
amplitude
rocks formed from the transformation of other rocks through pressure and temperature change or weathering.
metamorphic rocks
ultraviolet rays
With a satellite phone system, you can call anywhere in the
world
When waves bend due to a change in speed they
are called refraction waves
Describes how often waves passes a given point
frequency
The three types of rocks
igneous, metamorphic, and sedimentary
This light can be seen with the human eye
visible light
A satellite television system includes communication satellites and
satellite dish antennas
Destructive interference in a standing wave produces points with zero amplitude called
nodes
What are the properties of waves?
speed, amplitude, frequency, and wavelength
minerals and or lava
microwaves have shorter wavelengths and higher frequencies than
radio waves
Cell phones transit and receive signal using
microwaves
