Types of Waves
STATE THE TERM:
any disturbance that transfers energy from place to place
a wave
What is the crest?
the tallest part of a wave
Define the Term:
reflection
The bouncing back of a wave when it hits a surface and goes in a different direction.
Name the two types of wave movements?
Transverse waves
longitudinal wave
TRUE OR FALSE
Sound waves are electromagnetic waves
FALSE - they are mechanical waves
Name two types of waves
mechanical and electromagnetic waves
What is the wavelength of a wave?
the distance a wave travels before it starts to repeat
- the distance from crest to crest or trough to trough
Define the Term:
refraction
the bending of a wave as it enters a new medium at an angle
What is a standing wave?
a wave that appears to stand in one place
TRUE OR FALSE:
Sound waves cannot move through a vacuum
(can you explain why?)
STATE THE TERM:
one type of wave that moves through some type of matter
mechanical wave
Explain frequency
the number of complete wavelengths that pass a point in a given time
Define the term:
absorption
the bending of a wave as it enters a new medium at an angle
Define the Term:
Transverse wavesA wave that moves perpendicular to the direction in which the wave travels
Space is an example of a medium
FALSE - space is a vacuum
What does the term "vacuum" mean? Give an example.
example: space
what is the amplitude?
the height of a wave's crest.
(height from midpoint to crest)
Define the Term:
diffraction
The bending of a wave as it moves around an obstacle or passes through a narrow opening
Define the Term:
Longitudinal waves
a wave that travels in the same direction as the vibrations that produce it.
TRUE OR FALSE
The direction of the vibration determines what type of mechanical wave is produced
TRUE
Define the term:
electromagnetic wave
a type of wave that transfers a type of energy called electromagnetic radiation.
DRAW A WAVE ON THE WHITEBOARD AND LABEL THE PARTS
(hint: there are 4 parts)
:)
What is it called when two waves interact
Name the two types.
Interference
1. Constructive Interference
2. Destructive Interference
Define the term:
Resonance
An increase in the amplitude of a vibration when external frequencies match the object's frequency.
TRUE OR FALSE
You're going to ROCK this quiz tomorrow
TRUE!!!!!
