Question

Which of the following statement is incorrect regarding transverse wave?
1. Direction of disturbance and direction of propagation is always perpendicular.
2. Direction of disturbance and direction of propagation is always parallel.
3. Electromagnetic waves are transverse in nature.
4. Transverse wave are generally form in a medium that can sustain shearing strain.

Answer 1

Correct Answer - Option 2 : Direction of disturbance and direction of propagation is always parallel.

CONCEPT:

On the basis of the direction of propagation, waves are classified into two types:

• Longitudinal Waves: Those waves whose direction of propagation and direction of disturbance is always parallel.
  • These waves produced in a medium that can sustain compressive strain. 
  • Example Sound Wave
• Transverse Waves: Those waves whose direction of propagation and direction of disturbance is always perpendicular. 
  • These waves produced in a medium that can sustain shearing strain.
  • Example: Electromagnetic Waves.

EXPLANATION:

• In the transverse wave, the direction of disturbance and direction of propagation is always perpendicular.
• Electromagnetic waves are transverse in nature.
• Transverse wave generally forms in a medium that can sustain shearing strain.
• Since the statement of option 2 is wrong. Hence option 2 is correct.

• Electromagnetic waves are produced by an oscillating charged particle.
