Question

anything that gives off heat radiates ______ waves. this includes the human body!
o a x - ray
o b radio
o c infrared
o d gamma

Explanation:

• X - rays are high - energy electromagnetic waves used in medical imaging (like X - ray machines for bones) and not related to heat radiation from the human body.
• Radio waves are used for communication (e.g., radio, TV, mobile networks) and have low energy, not associated with heat radiation from warm objects.
• Infrared waves are a type of electromagnetic radiation. Objects that have a temperature above absolute zero emit infrared radiation. The human body, being warm, also radiates infrared waves.
• Gamma rays are very high - energy electromagnetic waves produced by nuclear reactions and radioactive decay, not related to the heat radiation from the human body.

Answer:

C. Infrared
