The table below shows the speed of sound waves from musical sound sources at 20°C. Wavelengths (m)
1.76
1.32
0.78
0.66
Frequency (Hz)
196
260
440
524
Wave Speeds (m/s)
344
344
344

Which conclusion can be made based on the information in the table?
O Wave speed and wavelengths can vary inversely to produce the same frequency
Frequency and wave speed can vary directly to produce the same wavelength.
O Wavelengths and frequency can vary inversely to produce the same wave speed.
O Frequency and wavelengths can vary directly to produce the same wave speed.

O Wavelengths and frequency can vary inversely to produce the same wave speed.

Explanation:

Analyzing the given data table, it is clear that the wave speed remains constant in every case. Since the wave speed does not change and has the same value in every instance. Therefore, the wavelength and frequency must vary to make the speed constant.

Now the data also indicates that whenever wavelength increases, the frequency decreases. While the frequency increases whenever the wavelength decreases. Hence, it can be concluded that the wavelength and the frequency are inversely proportional to each other.

So, the correct option is:

O Wavelengths and frequency can vary inversely to produce the same wave speed.

i believe the answer would be:
