The document contains 3 multiple choice questions about characteristics of sound waves and mechanical waves: 1) The speed of sound waves does not depend on the source generating them. 2) A mechanical wave where molecules oscillate perpendicular to propagation is a transverse wave. 3) When two waves traveling in the same direction are out of phase, destructive interference will result.

1. Question 1
