Detailed About MCQs

When heat results from radiation, energy are transmitted at the speed of light. Heat radiation travels at a speed of 3×108 m/sec. It follows a straight-line path. Thermal Radiation occurs through a vacuum or any transparent medium (solid or fluid). Speed of light c = 3×108 m/s.
