Definitions
What is the distance between two crests or troughs; or the distance between two compressions.
This is the definition of the term "wavelength".
What happens to waves of opposite wavelengths?
The waves cancel one another out.
What type of coding uses a pattern of dots and dashes to transfer information?
Morse Code
Sound waves are examples of what types of waves?
Longitudinal
Describe reflection.
Light waves bounce of an object.
What is the measurement from the midpoint of the wave to the peak or crest?
This is the definition of amplitude.
What happens to waves of the same or similar wavelengths?
The waves will increase in amplitude.
What type of coding uses a pattern of 1s and 0s to transmit information?
Binary
What is directly related to a sounds amount of energy?
Amplitude.
What is refraction?
Light moves through two mediums and appears to be bent.
What is the wave type that carries objects and energy in the same direction?
Longitudinal Waves
What is the best model of a transverse wave?
A. place a toy inside a bathtub filled with water
B. attach a rope to a wall and move it up and down
C. send toys down a ramp
Attach a rope to a wall and move it up and down.
Compare Binary and Morse code.
They both use patterns to represent letters.
Sound waves are created through what?
Vibrations.
What color absorbs all other colors and what is an effect of this phenomenon?
Black. It causes this color to hold heat.
What is the wave type that moves objects up and down, while carrying energy forward?
Transverse Waves
What wave type experiences the most energy?
(hint: use amplitude and wavelength)
What is the first name of the inventor of Morse Code?
Samuel.
What is the difference in the peak and trough in a longitudinal wave?
The peak is more compressed and has more energy than the trough.
Name one object that is opaque, translucent, and transparent.
*Answers will vary*
Which term means "a disturbance that transmits energy"?
This is the definition of the term "wave".
Mechanical waves require what to move?
Explain how cell phones use binary code to transmit a text message.
A message is typed out, coded into a pattern of 1s and 0s, send to a receiver, and translated back into the original message.
How is the sound of an object related to the type of wave it makes? Ex: a large drum will make a wave that is..... compared to a smaller drum.
The larger the object is, the greater amplitude it will have.
Light waves are examples of what types of waves?
Electromagnetic.
