COMEDK · Physics · 12. Thermal Properties of Matter
In which mode of transmission, the heat waves travel along straight line with the speed of light?
- A Thermal radiation
- B Forced convection
- C Natural convection
- D Thermal conduction
Answer & Solution
Correct Answer
(A) Thermal radiation
Step-by-step Solution
Detailed explanation
Thermal radiation is the process by which heat is transferred in the form of electromagnetic waves. These waves travel through a vacuum or a medium at the speed of light, \(c \approx 3 \times 10^{8}\) m/s, and propagate in straight lines. Answer: Thermal radiation
