Question

Energy is not carried by :
1. transverse progressive wave
2. longitudinal progressive wave
3. electromagnetic wave
4. stationary waves

Answer 1

Correct Answer - Option 4 : stationary waves

CONCEPT:

• Wave is a disturbance that transfers energy from one point to another point in the medium due to vibration of molecules of the medium and the energy is transferred without the actual movement of the particles in the medium the particles vibrate about their equilibrium position only.
• The disturbance being handed over from one particle to the next.
• In a wave, both information and energy propagate (in the form of signals) from one point to another but there is no motion of matter as a whole through a medium.

EXPLANATION :

• From the given options the standing waves are the waves that are confined to a particular region.
• All the other waves change their position with respect to time hence they transfer energy from one point to another point, only standing waves will be trapped in a particular region hence it can't carry energy.
• Hence, option 4 is the answer
