Concept explainers
Interpretation:
With increase in temperature the light emitted by a heated, glowing object is needs to be explained.
Concept introduction:
In 1905 to explain

Answer to Problem 42A
With increase in temperature the object acquire more energy. Hence, the color of the object is changed.
Explanation of Solution
The temperature of an object is the measure of the average kinetic energy of its particles. On heating objects emit light. As the object gets hotter and it possesses larger amount of energy. Hence, it releases different colors of light. Various colors resemble different frequencies and wavelength.
The wavelength of the heated object depends on the temperature. Hence, the color of emitted light is different.
