Detailed Solution
Download Solution PDFThe correct option is 'C'
- In music, as frequency increases, wavelength decreases.
- If a note has a very low frequency, it will have a very long wavelength.
- If the frequency of a pitch is very high, its wavelength will be very short.
- Hence frequency and wavelength are harmonious in music
Key Points
| Music | Noise |
