In the introduction of this activity, we mentioned the temperature of your home on hot and cold days. Your body is kept warm in your home primarily by two ways: by direct contact with the air around you and by absorbing infrared light that is radiated from the walls. As you have seen in this activity, the light that is radiated from an object depends almost solely on the temperature of the object. Based on what you have learned here, what is one reason for feeling warmer in your house on a summer day versus a winter day even though your thermostat is set the same?
a - The walls of the house are warmer during the summer. Therefore, they radiate more infrared light that can serve to warm our body.
b - The walls of the house are warmer during the summer. Therefore, they radiate more visible light that can serve to warm our body.
c - The walls of the house are warmer during the summer. Therefore, they radiate more ultraviolet (UV) light that can serve to warm our body.
d - The temperature of the walls of the house has no effect on the light they radiate.
