Understanding Musical Instruments and Sound Waves

What type of wave is sound primarily classified as?

• Surface wave

• Longitudinal wave

• Electromagnetic wave

• Transverse wave

What phenomenon occurs when a wave is reflected back on the same path?

• Reflection

• Diffraction

• Transmission

• Refraction

What is the term for a wave that appears to stay in one place with changing amplitude?

• Progressive wave

• Resonant wave

• Standing wave

• Traveling wave

What are the points on a standing wave that do not move called?

• Nodes

• Troughs

• Crests

• Antinodes

What is the role of antinodes in a standing wave?

• They are points of maximum amplitude

• They do not affect the wave

• They are points of no movement

• They are points of minimum amplitude

What happens to the wave at a closed end of a pipe?

• It passes through

• It is inverted

• It is reflected without inversion

• It dissipates

What is the simplest form of a standing wave known as?

• Third harmonic

• Overtone

• Fundamental

• Second harmonic

How is the frequency of the second harmonic related to the fundamental frequency?

• The same as the fundamental frequency

• Twice the fundamental frequency

• Half the fundamental frequency

• Three times the fundamental frequency

What determines the fundamental frequency of a string in a musical instrument?

• The string's length, mass, and tension

• The musician's skill

• The string's color

• The type of instrument

Why can't a pipe with one closed end have even-numbered harmonics?

• Due to lack of nodes

• Due to lack of antinodes

• Wave requirements for nodes and peaks

• Interference patterns do not allow it
