| 3. Refraction |
| 4. Free vibration |
| 5. Resonance |
| 6. Diffraction |
| Select the correct answer using the codes given below. |
A) 1, 3 and 5
B) 1, 2, 4 and 6
C) 2, 3, 5 and 6
D) All of these
Correct Answer: A
Solution :
[a] Sound is a vibration that propagates as a mechanics wave of pressure and displacement through some medium. The denser the medium, the more the speed of propagation of sound. Few of the properties of sound wave are reflection, refraction, resonance etc. The basic properties of sound are pitch, loudness and tone. It is measured in decibel.
