Question

What type of motion do the sound waves move in while travelling through air?
1. Oscillating
2. Linear
3. Reciprocating
4. Rotatory

Answer 1

Correct Answer - Option 1 : Oscillating

The correct answer is Oscillating.

• Oscillatory motion can be termed as the repeated motion in which an object repeats the same movement over and over.
• In a longitudinal wave, such as a sound wave, the particles oscillate along the direction of motion of the wave.
• Surface waves, such as water waves, are generally a combination of a transverse and a longitudinal wave.
• oscillations determine the sound of a musical instrument, the color of a rainbow, the ticking of a clock, and even the temperature of a cup of tea.
• A mechanical oscillation is a repeating movement, an electrical oscillation is a repeating change in voltage and current.
