Answer 1

Answer:

Explanation:

ACTUALLY YOU UNDERSTAND IT EASILY .

WHEN WE START HEATING A BODY IT STARTS CHANGING ITS COLOUR ACCORDING TO TEMPERATURE GAINED BECAUSE LIGHT OF SPECIFIC WAVELENGTH AND FREQUENCY ARE RADIATED IN DISCONTINUOUS MANNER AS PER PLANCK QUANTUM THEORY.

RED COLOUR CORRESPONDS TO LEAST TEMPERATURE AND BLUE COLOUR CORRESPONDS TO MAXIMUM TEMPERATURE. AND SO THE COLOUR OF THE BODY CHANGES GRADUALLY WITH RESPECT TO TEMPERATURE FROM DULL RED TO BLU.

YOU MAY ALSO REFER TO BLACK BODY RADIATION CURVE FOR MORE UNDERSTANDING.
