Quiz zum Vortrag
Two sound waves interfere. How is the total waves amplitude calculated based on the amplitudes of each individual wave?
- The amplitude of the total wave at each point is the sum of the amplitudes of each individual wave at that point.
- The amplitude of the total wave at each point is the subtraction between the amplitudes of each individual wave at that point.
- The amplitude of the total wave at each point is a complicated function of the amplitudes of each wave at that point.
- The amplitude of the total wave at each point is found by summing the absolute values of the amplitudes of each individual wave at that point.
- The amplitude of the total wave at each point is found by multiplying the amplitudes of each wave at that point.
Two sound waves of frequencies f₁ and f₂ interfere. The difference between the frequencies is small compared to the frequencies themselves. What is the beat frequency of the total wave?
- |f₁ - f₂|
- |f₁ - f₂|/2
- 2|f₁ - f₂|
- f₁ + f₂
- (f₁ + f₂)/2
A musician is trying to tune his instrument by comparing the note produced by its instrument to the note produced by a known source. The known source is producing a note with a frequency of 440 Hz. If the musician hears a beat frequency of 2 Hz, what is the frequency of the note produced by the instrument? Choose the best answer.
- 442 Hz or 438 Hz
- 4 Hz
- 336 Hz
- Its either 444 Hz or 336 Hz
- 444 Hz
