resonance

The loudness of a sound is called

• the sound wave
• the volume
• the amplitude
• the pitch

The same sound will seem louder if it travels through which of the following?

• solid materials

• liquids

• air

• solids, liquids, or gases will sound the same

How is sound produced by these instruments?

• Striking the surface
• vibrating columns of air
• plucking the strings

When two waves combine to form a new wave with a smaller amplitude, it is called 

• Refraction
• Constructive Interference
• Resonance
• Destructive Interference

A tuning fork starts to vibrate when a certain note is played on the piano, This is an example of _______.

• resonance
• refraction
• diffraction
• reflection

What occurs when vibrations traveling through an object match the object's natural frequency?

• reflection
• diffraction
• resonance
• refraction

True or False: Sound needs a medium.

• True

• False

The distance from the beginning of one compression to the beginning of the next compression is called a -----

• Rarefaction

• Frequency

• Wavelength

• Compression

The speed of sound depends on these two things:

• The type of medium and the temperature of the medium

• Speed of the medium and temperature of the medium

• Temperature of the medium and sound of the medium

• None of the above

Natural frequency is best described as

• the frequency at which an object naturally vibrates at when it is disturbed

• a vibration that can be heard in the wild

• the radio frequency that astronauts naturally use when travelling into space

• the material used to make a swing
