|
Can a light wave be transmitted through a vacuum?
|
Yes
|
|
|
A wave in which particles of the medium move at right angles to the direction of the wave is called a
|
transverse wave
|
|
|
The number of complete wave cycles per unit time is
|
frequency
|
|
|
Frequency times wavelength equals
|
speed
|
|
|
The apparent breaking in two of a pencil that is placed diagonally partway into water is caused by
|
refraction
|
|
|
You can hear a sound that is produced out of sight around the corner of a building because of
|
diffraction
|
|
|
The speed of sound in steel is greater than it is in air because steel is
|
more dense than air
|
|
|
The maximum distance of molecules in a medium from their rest position is called
|
amplitude
|
|
|
The low point of a wave is the
|
trough
|
|
|
A wave in which the motion of the medium is parallel tot he direction of the wave is called a
|
longitudinal wave
|
|
|
The distance between two consecutive crests of a wave is called
|
wavelength
|
|
|
The line perpendicular to a barrier is called the
|
normal
|
|
|
The unit used to measure frequency is called the
|
hertz
|
|
|
The bending of a wave around an edge of an obstacle is called
|
diffraction
|
|
|
The interaction of two or more waves that arrive at the same place at the same time is called
|
interference
|
|
|
The bending of a wave due to a change in speed is called
|
refraction
|
|
|
When a wave strikes a barrier and bounces back, it is called
|
reflection
|
|
|
The frequency at which a standing wave occurs is called the
|
resonance frequency
|
|
|
A wave that does not appear to be moving is called a
|
standing wave
|
|
|
Sound waves travel as
|
transverse waves
|
|
|
A wave that is carrying a large amount of energy has
|
a large amplitude and high frequency
|
|
|
Any substance or region through which a wave is transmitted is called a
|
medium
|
|
|
A wave in which there are stationary nodes and antinodes is called a
|
standing wave
|
|
|
A wave that is bounced back is called a
|
reflected wave
|
|
|
In a given medium, the speed of a wave is
|
constant
|
|
|
The incoming wave is the
|
incident wave
