Characteristics of sound waves: JAMB Physics Past Questions and Answers
What the JAMB syllabus covers in Characteristics of sound waves
Our summary: Noise and musical notes, pitch and loudness, vibrating strings, and air columns in pipes.
- Noise and musical notes
- Quality, pitch, intensity and loudness and their application to musical instruments
- Simple treatment of harmonics and overtones produced by vibrating strings and their columns ($F_0 = \frac{1}{2L}\sqrt{\frac{T}{m}}$)
- Acoustic examples of resonance
- Frequency of a note emitted by air columns in closed and open pipes in relation to their lengths
Objectives

- analyse quality, pitch, intensity and loudness of sound notes;
- evaluate the application of (ii) above in the construction of musical instruments;
- identify overtones by vibrating strings and air columns;
- itemize acoustical examples of resonance;
- determine the frequencies of notes emitted by air columns in open and closed pipes in relation to their lengths.
