Question

The waves which are produced in air are always _______.
1. Matter Waves
2. Transverse Waves
3. Longitudinal Waves
4. Electromagnetic Waves

Answer 1

Correct Answer - Option 3 : Longitudinal Waves

The correct answer is Longitudinal Waves.

• Longitudinal Waves
  • A wave in which the particles of the medium vibrate in the same direction of propagation of the wave is called a longitudinal wave.
  • It can be produced in all three media such as solids, liquids, and gases.
  • The waves which are produced in the air are always longitudinal waves.
  • Example: The waves produced in spring when it is pushed and pulled at one end are longitudinal waves.

​

• Matter Waves
  • The waves associated with moving particles like electrons, protons, etc. are called matter waves.
• Transverse Waves
  • A wave in which the particles of the medium vibrate perpendicular to the direction of propagation of the wave is called a transverse wave.
  • It can be produced only in solids.
  • Light is a transverse wave.
• Electromagnetic Wave
  • The waves which require no medium to propagate are called an electromagnetic wave.
  • X-rays, radio waves, ultraviolet waves are examples of electromagnetic waves.
