(a)
To graph: The equation
(a)
Answer to Problem 46E
The graph
Explanation of Solution
Given information: Music: The frequency of a sound wave is called its pitch. The pitch p of a musical tone and its wavelength w are related by the equation
Calculation:
(b)
What lines are close to the maximum values for the pitch and the wavelength?
(b)
Answer to Problem 46E
Both axis are close
Explanation of Solution
Given information: Music: The frequency of a sound wave is called its pitch. The pitch p of a musical tone and its wavelength w are related by the equation
Calculation:
Both axis are close
(c)
What happens to the pitch of the tone as the wavelength decreases?
(c)
Answer to Problem 46E
As the wavelength decreases the pitch increases
Explanation of Solution
Given information: Music: The frequency of a sound wave is called its pitch. The pitch p of a musical tone and its wavelength w are related by the equation
Calculation:
The graph represents an inverse variation.
As one value increases the other decreases and
As the wavelength decreases the pitch increases.
(d)
What happens to the pitch of the tone if the wavelength is doubled?
(d)
Answer to Problem 46E
If we double the wavelength then the pitch is halved
Explanation of Solution
Given information: Music: The frequency of a sound wave is called its pitch. The pitch p of a musical tone and its wavelength w are related by the equation
Calculation:
The opposite reaction
If you double the wavelength,
Then the pitch is halved.
