Answer 1

The ratio of the wavelength of the red note and blue note is 2: 1 and the correct option is D.

Wavelength is the distance between two consecutive crests and troughs.

Mathematically, we can write wavelength as -

λ = c/ν

where -

λ: wavelength

ν: frequency

Given are the two notes as shown in the image.

For the red note, the distance between the consecutive crests is twice that of the distance between the consecutive crests in the case of the blue note. We can write the ratio of the wavelengths as -

λ(R)/λ(B) = 2/1

Therefore, the ratio of the wavelength of the red note and blue note is 2: 1 and the correct option is D.
