What do you think the answer to the question is?
The ratio of the wavelengths of the two notes is 2:1 option fourth 2 to 1 is correct.
<h3>What is wavelength?</h3>
The wavelength is the distance between two successive troughs or crests. The highest point on the wave is the crest, while the lowest point is the trough.
We have two notes
Number of cycle for blue = 8
Number of cycle for red = 4
Ratio = 8:4 = 2:1
Or
2 to 1
Thus, the ratio of the wavelengths of the two notes is 2:1 option fourth 2 to 1 is correct.
