Physics of Sound Quiz

Mickey and Minnie are in a band in Disney. Their conductor, Donald, explains that when they play their instruments, the frequency of the sound produced affects how high or low the sound seems. What is the relationship between the frequency of the sound they produce and the pitch that is heard?

• Frequency and pitch are unrelated

• Frequency and pitch are inversely related

• Frequency and pitch are directly related

• Frequency and pitch are only related in certain situations

Donald and Daisy are in a music class at Disney World. Professor Denning explains (by quacking) that the frequency of sound waves affects the pitch of the sound we hear. Donald is confused. How could Daisy explain to him how frequency and pitch are related in this context?

• Daisy could tell him when she plays a note on her violin with a higher frequency, it produces a higher pitch, while when Minnie plays a note on her piano with a lower frequency, it produces a lower pitch.

• She could show Donald that when he plays a note on his flute with a lower frequency, it produces a higher pitch.

• Daisy could explain that when Mickey plays a note on his violin with a higher frequency, it produces a lower pitch.

• She could tell him that frequency and pitch are not related, regardless of what instrument anyone (except for Goofy) plays.

Mickey, Donald, and Goofy are in a music class at Disney. Their teacher, Minnie, explains that the amplitude of a sound wave affects its loudness. How does the amplitude affect the loudness of a sound?

• The loudness of a sound increases with the increase in amplitude.

• The loudness of a sound is unrelated to the amplitude.

• Amplitude has no effect on the loudness of a sound.

• The loudness of a sound decreases with the increase in amplitude.

Mickey, Donald, and Goofy are in a sound recording session for a new Disney movie. Their director explains that the amplitude of a sound wave affects its loudness. How would you describe this relationship in the context of their recording session?

• The relationship between amplitude and loudness in their recording session is random and unpredictable.

• Amplitude and loudness are not related in their recording session.

• As the amplitude of a sound wave increases in their recording session, the loudness of the sound decreases.

• As the amplitude of a sound wave increases in their recording session, the loudness of the sound also increases.

Mickey, Donald, and Goofy are working on a new musical instrument in the Disney workshop. They are trying to understand the relationship between the wavelength and frequency of the sound it produces. Mickey thinks they are inversely proportional, Donald thinks they are not related, and Goofy thinks they are directly proportional. Who is correct?

• Mickey

• Donald

• Goofy

• None of them

Mickey, Minnie, and Donald are creating a new musical show at Disney. They are trying to understand the concept of wavelength in the context of sound waves for their show. Can you explain it to them using a real-world scenario?

• The speed of sound in a medium, like when they hear the sound of a Disney parade passing by

• Distance between two consecutive compressions or rarefactions, like the distance between two consecutive peaks of a wave in the Disney's artificial ocean

• The amplitude of the sound wave, like the loudness of the Disney theme song they are listening to

• The frequency of the sound wave, like the pitch of the Disney songs they are listening to

Chip and Dale are studying the physics of sound at Disney World and they come across a term 'phase'. In the context of a concert they attended at the Magic Kingdom, where the sound waves were traveling from the stage to their seats, what would 'phase' refer to?

• The color of the sound wave they heard

• The speed of the sound wave from the stage to their seats

• Position of a point in time on a waveform cycle of the music they heard

• The temperature of the sound wave at the concert

Mickey, Donald, and Goofy are working on the sound effects for their new Disney movie. They are discussing the concept of phase and its significance in sound waves for creating the perfect sound effects. How would you describe this concept to them?

• The concept of phase in sound waves refers to the volume of the sound.

• Phase in sound waves has no significance and does not affect the overall sound quality.

• The concept of phase in sound waves refers to the position of a point in the wave cycle at a given time. It is significant in sound waves as it determines the interference and reinforcement of waves, affecting the overall sound quality and perception.

• Phase in sound waves refers to the frequency of the sound.

Mickey, Donald, and Goofy are in a music class at Disney learning about sound. They are discussing the relationship between periods and waveforms in sound. What conclusion do they reach?

• They conclude that periods and waveforms in sound are directly related

• They conclude that waveforms in sound have no impact on periods

• They conclude that periods and waveforms in sound are completely unrelated

• They conclude that periods in sound are longer than waveforms

Anna and Elsa are studying the concept of periods and waveforms in the context of sound waves. They decide to apply this concept to a real-world scenario. They observe a piano string vibrating and producing sound in a Disney concert performance of 'Let it Go'. How would they explain the concept of periods and waveforms in this context?

• They would say that periods are related to the color of the sound wave produced by the piano string

• They would say that waveforms are the number of sound waves produced by the piano string in a given area

• They would say that the concept of periods and waveforms in sound waves relates to the time it takes for the piano string to complete one full vibration (period) and the shape of the wave produced (waveform), respectively.

• They would say that periods and waveforms have no impact on the sound waves produced by the piano string
