How do ultraviolet and infrared radiation differ? Do you think your body emits any radiation in the ultraviolet range? Explain.
What will be an ideal response?
Infrared radiation lies between 0.76 and 100 ?m whereas ultraviolet radiation lies between the wavelengths 0.01 and 0.40 ?m. The human body does not emit any radiation in the ultraviolet region since bodies at room temperature emit radiation in the infrared region only.
