A loud sound is vibrated with more force than a soft sound. The amount of energy in a compression wave is known as the _________.
Amplitude
Sound energy is an example of what type of energy?
Mechanical Energy
The part a sound wave that is spread out and has decreased pressure is called what?
Rarefaction
What are the number wavelengths that pass any point in a second called?
Frequency
Sound Waves travel the fastest through what?
Solids. This is because the molecules in a solid are packed tightly together, allowing sound waves to transfer energy more quickly between them compared to liquids or gases.
The part a sound wave that is pushed together and has a lot of pressure is called what?
Compression
The amount of vibrations a sound wave has is called what?
Amplitude
Pitch is determined by the ________ of a vibrating object?
Frequency
Sound waves travel the slowest through what?
Gases. This is because the molecules in a gas are spaced far apart, making it harder for sound waves to transfer energy from one molecule to the next, resulting in a slower travel speed compared to liquids and solids.
Which types of waves will travel further? Low frequency or high frequency?
Low Frequency. Think LOW frequency LAST longer don’t run out of steam (energy) as quickly.
True or False. A HIGH amplitude has LESS vibrations and a SOFT sound.
False. A HIGH amplitude has MORE vibrations and a LOUD sound.
True or False. A LOW amplitude has LESS vibrations and a SOFT sound.
True. A LOW amplitude has LESS vibrations and a SOFT sound.
What would be the speed of sound traveling through air? Fast, Medium, or Slow?
Slow!
Which types of waves will travel not travel as far? Low Frequency or High Frequency?
High Frequency. Think HIGH frequency run out of energy faster. Think about doing jumping jacks.
What would be the speed of a sound wave in a book? Fast, Medium, or Slow?
Fast!
What is the highness or lowness of the sound called?
Pitch
How many times faster does sound travel through a liquid than gas?
4 times FASTER!
What would be the speed of sound traveling through the ocean? Fast, Medium, or Slow?
Medium!
How does a string instrument create sound?
Someone touches the strings, in order to MOVE to create vibrations.
How do woodwind instruments create sound?
Someone uses their MOUTH/AIR to create vibrations.
How do percussion instruments create sound?
Someone HITS a hard surface to create vibrations.
What is the STRENGTH of a sound wave called?
Resonance
True or False. If a wave has a HIGH amplitude and LOUD sound, the waves will be TALL in height.
True. If a wave has a HIGH amplitude and LOUD sound, the waves will be TALL in height.
The distance from one compression to the next compression, OR one rarefaction to the next rarefaction is called?
Wavelength
What can be described as a disturbance moving through a solid, liquid, or gas?
Sound Wave
