Q62 / 79 · NEST (NISER) 2026 · Physics

Among the following, the waves responsible for energy transfer in vacuum are

  • A
    sound waves.
  • B
    seismic waves.
  • C
    SONAR waves.
  • Correct answer
    D
    infrared waves.

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.

Hence, the correct answer is option: 'D'.
