Heat waves_____________________?
Correct answer: D. Both B. and C.
- A. Cannot pass through vacuum
- B. Travel in straight line
- C. Can be reflected by a mirror
- D. Both B. and C.
Explanation
Heat waves are electromagnetic radiation, so they can travel through a vacuum, propagate in straight lines, and undergo reflection from surfaces such as mirrors. Therefore both statements b and c are true.
