How do longitudinal waves move?
The waves move perpendicular to the energy (opposite directions)
The waves move parallel to the energy (same direction).
They move around in circular motions around seismic waves and are similar to supersonic waves
They don't move at all.
How do transverse waves move?
The waves move parallel to the energy (same direction).
They don't move at all due to seismic waves.
The waves move perpendicular to the energy (opposite directions
They only move around at night
How are waves related to energy?
Waves and energy are both in the electromagnetic cylinder.
They are not related at all.
Waves carry energy
Energy travels in waves.

nothing happens
The sound decreases
The sound increases
True or false- As frequency increases, the wavelength decreases.
True :)
False :(

Pick an example below to match the definition - When a sound wave is reflected, the particles bounce off of a surface and in another direction.
Echos and sonar
Bats use echolocation to navigate and find food in the dark.
Sonar can be used by submarines and ships to locate objects nearby and/or measure the distance to the bottom of the sea.
The changing sound of a siren as an ambulance drives by at high speed
Echolocation
is the use of sound waves and echoes to determine where objects are in located. When a wave reaches an obstacle a portion of the wave will bounce back and a portion of the wave travels through the obstacle.
Pick on of the examples below to match the definition(Do not pick this)
Bats use echolocation to navigate and find food in the dark.
Sonar can be used by submarines and ships to locate objects nearby and/or measure the distance to the bottom of the sea.
Owls for instance are able to communicate across long distances due to the fact that their long-wavelength hoots are able to diffract around forest trees
Diffraction
A change in direction (bending) of waves as they pass through an opening or around a barrier in their path.
Pick an example below to match the definition(Do not pick this option)
The changing sound of a siren as an ambulance drives by at high speed
Owls for instance are able to communicate across long distances due to the fact that their long-wavelength hoots are able to diffract around forest trees
Bats use echolocation to navigate and find food in the dark.
