Define the term "Wave" and provide 1 example.
A disturbance that carries energy through matter or space
Ex: Light waves, radio waves, mechanical waves, electromagnetic waves, etc.
100
_______ may spread out as a wave travels.
Energy
Ex. Standing in front of a speaker
100
True or False: Particles only vibrate up and down.
False
Particles can vibrate either up or down or back and forth
100
Please label the following terms on a wave:
Amplitude, Trough, Wavelength, and Crest
100
The bouncing back of a wave when it meets a surface or boundary is called ___________.
Reflection
200
the matter through which a wave travels is called a(n) _________.
Medium
200
True or False: The bigger the wave, the less energy it carries.
False
The bigger the wave, the more energy it carries
200
Waves are classified according to the __________ in which the particles move.
direction
200
Define the terms period and frequency, and include any new units that are associated.
Period- The time it takes a wave to pass a given point
Frequency- how rapidly vibrations occur in the medium (The inverse of a period)
F = frequency Units: hertz (Hz)
200
__________ is when a wave bends as it passes from one medium to another.
Refraction
300
Water, Earth, and Air are all examples of what?
A Medium
300
Most waves are caused by __________.
Please provide an example.
Vibrating objects
Ex. Sound Waves= Vibrating vocal cords
Electromagnetic Waves= vibrating charged particles
300
In which type of wave do the particles move parallel to the wave motion?
Please provide an example.
Longitudinal
Ex. Sound Waves
300
True or false:
The shorter the wavelength the more energy
True
300
What term is associated with the definition below:
A change in direction of a wave when it passes an edge or obstacle. Bends round the edge
Diffraction
400
A tsunami wave is an example of what specific type of wave?
A mechanical wave
400
What wave concept is conveyed in the GIF below?
Particle motion in a wave
400
Define the term transverse wave and draw what the wave looks like.
The particles move perpendicular to the wave direction
Ex. Electromagnetic Waves
400
Both Amplitude and Wavelength measure __________.
distance
400
When several waves in the same location combine to produce a single wave different from the original waves
Constructive - when amplitude increases
Destructive - when amplitude decreases
Interference
500
A radio wave, as well as light from the sun, are both an example of what specific type of wave?
An electromagnetic wave
500
Explain how sound waves would travel from a large bass speaker with a person standing in front of it.
The sound energy will hit the person and the waves will spread out as they travel around the room.
500
Please label the following terms on either a transverse or a longitudinal wave.
Rarefaction, Trough, Compression, and Crest
500
True or false:
The weaker the amplitude, the more energy
False
The greater the amplitude, the more energy
500
Interference of light waves creates ______________.
Interference of sound waves creates _______.
colorful displays
beats
