Waves
This is what waves transmit.
This is what the energy of a mechanical wave travels through.
What is a medium?
The two major parts of a transverse wave are called this.
Sound is this type of mechanical wave.
What is longitudinal?
This is what causes a sound wave to echo.
What is reflection?
These are the two types of waves.
What are mechanical and electromagnetic?
The vibration is parallel to the direction of propagation in this type of wave.
What is longitudinal?
This is the number of waves that pass a point per second.
What is frequency?
This is the type of medium that sound travels the fastest in.
What is solid?
This is what causes the Doppler Effect.
What is relative motion (source of sound and observing moving towards or away from each other)
These are the two types of mechanical waves.
What are transverse and longitudinal?
This measures the amount of energy in a wave.
What is amplitude?
This is the relationship between frequency and wavelength for a wave.
What is inverse?
This is what we call the perception of frequency of a sound.
This is when an object is forced to vibrate by another object, resulting in a louder sound.
What is Resonance?
What is destructive interference?
This is a wave with nodes and antinodes/loops, created by wave reflection and interference.
What is a standing wave?
This is the position of an undisturbed medium.
What is equilibrium?
What are compression and rarefaction?
These are the perceived frequency/pitch changes of a sound due to the Doppler Effect.
What are higher when moving towards observer and lower when moving away from observer?
What is 0.067 seconds?
This the frequency of a 15 m wave traveling at a speed of 47 m/s.
What is 3.1 Hz?
This is the wavelength of a 3 loop standing wave in a spring that is stretched to a length of 8 m.
What is 5.3 m?
This is the time it takes for the echo if Mrs. Hayes is hiking in Providence canyon and shouts at the canyon wall 100 m away when the speed of sound is 335 m/s.
What is 0.6 seconds?
This is the temperature of the air if the speed of sound is 341 m/s.
What is 15.8 (16) degrees?
