How is it that we can "feel" radiation from the Sun that we cannot see?
What will be an ideal response?
Infrared radiation is not detected in the eyes, as is visible radiation, but on the
skin. The infrared radiation is felt as heat, similar to what you might feel over a gas burner
after the gas has been turned off. The radiation transfers energy to the skin, which is how
the infrared radiation is detected.
