(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.

If the limit does not exist, write DNE: Hint: Remember the first thing you check when you are looking at a limit of a quotient is the limit value of the denominator. 1. If the denominator does not go to 0, you should be able to right down the answer immediately. 2. If the denominator goes to 0, but the numerator does not, you will have to check the sign (±) of the quotient, from both sides if the limit is not one-sided. 3. If both the numerator and the denominator go to 0, you have to do the algebraic trick of rationalizing. So, group your limits into these three forms and work with them one group at a time.
