Answer :
To find the wavelength of sound waves, we use the formula:
[tex]\[ \text{Wavelength} = \frac{\text{Speed of Sound}}{\text{Frequency}} \][/tex]
Let's plug in the given values:
1. The speed of sound in dry air at room temperature is 340 meters per second (m/s).
2. The frequency of the sound waves is 220 Hertz (Hz).
Now, divide the speed of sound by the frequency to find the wavelength:
[tex]\[ \text{Wavelength} = \frac{340 \, \text{m/s}}{220 \, \text{Hz}} \][/tex]
[tex]\[ \text{Wavelength} \approx 1.55 \, \text{meters} \][/tex]
Therefore, the wavelength of the sound waves is approximately 1.55 meters. So, the correct option is:
A. 1.55 m
