Question

Which of the following do waves transfer

Answer 1

Answer:

The correct answer is : 2- Energy.

Explanation:

• Waves are produced due to vibration or movement of molecules about their mean position in response to any disturbance generated on them.
• The disturbance transmits energy into the stationary molecules present in a medium.
• After taking up this energy the stationary molecules begin to vibrate about their mean position, hits the molecules next to it and transmit its energy to them.
• This process continues and eventually the energy gets transmitted through all the stationary molecules present in medium resulting in the generation of a wave.
• However, waves does not always require a medium to travel, but vibration or oscillation is necessary. Based on this two types of waves are:

1. Electromagnetic Waves (Light) : Here the electric and magnetic fields oscillates with respect to each other and generates a wave.
2. Mechanical Waves (Sound) : It requires a medium to travel and the waves moves by episodes of compressions and rarefactions.

• Based on direction of vibration, waves are of two types:

1. Longitudinal waves - Vibration occurs in a direction that is parallel to the direction of motion of the wave.
2. Transverse waves - Vibration occurs in a direction that is perpendicular to the direction of motion of the wave.
