Question

6. According to the lab manual, how do you find the experimental) wavelength of sound for the 512 Hz tuning fork? a. The wavelength is the position of the small pipe when you hear the loudest sound. b. Take the average value of the differences in positions where resonance occurs. C. Take double the average value of the difference in positions where resonance occurs. d. Input the speed of sound from equation 3 and the frequency, into equation 2 7. What is another name for the "inverse of frequency", (1/f)? a. period b. Hertz c. speed of sound d. wavelength 8. In a graph of wavelength vs. inverse of frequency ("y" vs. "x"), what is the slope equal to? a. (1/f/ a b . Nf c. 1/f d. v 9. What are the (SI) units of the slope of a plot wavelength vs. the inverse of frequency (y" vs. "X")? a. m/ s b . s/m c. Hz d. m/s² 10. In the empirical equation for the speed of sound from the lab manual (equation 3), what units must Tebe? a. m/s b. °C c. K d. s

please help with answering these

Answer 1

PROBLEM 7:

The period of oscillation is given by

$T=\frac{1}{f}$

So, the another name for the given quantity is 'period'.

PROBLEM 8:

The slope is given by

$m=\frac{y}{x}=\frac{\lambda}{1/f}=\lambda f=v$

Where v is the speed of the wave.

So, the correct answer is 'v'.

PROBLEM 9:

The SI unit of the velocity is 'm/s'.

PROBLEM 10:

In the emperical equations the temperature was used in the units of 'oC'.
