Question
 Identify the electromagnetic wave which is also known as heatwaves.
✓

Answer

  1. Infrared Waves
Explanation:
Infrared waves are heat radiations also known as heatwaves. These waves are produced by hot bodies and molecules. They do heating because water molecules present in most of the materials readily absorb infrared waves and their thermal motion increases, so they heat themselves and also heat their surroundings.
