Question

Which of the following properties of a sound wave determine its "pitch"? A) amplitude B) distance form source to detector C) frequency D) phase E) speed To produce beats it is necessary to use two waves: A) traveling in opposite directions B) of slightly different frequencies C) of equal wavelengths D) of equal amplitudes E) whose ratio of frequencies is an integer The "A" on a trumpet and a clarinet have the same pitch, but the two are clearly distinguishable. Which property is most important in enabling one to distinguish between these two instruments? A) intensity B) fundamental frequency C) displacement amplitude D) pressure amplitude E) harmonic content A magnetic field exists between the plates of a capacitor: A) always B) never C) when the capacitor is fully charged D) while the capacitor is being charged E) only when the capacitor is starting to be charged

Explanation / Answer

13). Pitch of the sound wave is determined by the "amplitude" of sound waves.

Hence correct option: A). amplitude

14). To produce beats, it is necessary for the waves to have atleast slight difference in frequency.

Hence correct option: B). of slightly different frequencies.

15). Correct option: B). fundamental frequency

16). Correct option: D). only when the capacitor is starting to be charged
