Among the following, the waves responsible for energy transfer in vacuum are
Options
- Asound waves.
- Bseismic waves.
- CSONAR waves.
- Dinfrared waves.
Correct answer
D. infrared waves.
Step-by-step solution
Mechanical waves such as sound waves, seismic waves, and SONAR waves require a material medium for their propagation and cannot travel through a vacuum. Infrared waves are electromagnetic waves. Electromagnetic waves do not require any material medium for their propagation and can easily travel through a vacuum, transferring energy. Therefore, infrared waves are responsible for energy transfer in vacuum. Answer: infrared waves.
