Black Body Radiation: Understanding the Relationship Between Temperature and Electromagnetic Radiation Emission and Abso

What happens to the rate of infrared radiation emission as the temperature of a body increases?

• It fluctuates randomly.

• It decreases.

• It remains constant.

• It increases.

What is a characteristic of a perfect black body?

• It emits no radiation.

• It absorbs all incident radiation.

• It reflects all radiation.

• It only absorbs visible light.

If an object absorbs infrared radiation at the same rate it emits, what happens to its temperature?

• It increases.

• It fluctuates.

• It decreases.

• It remains constant.

What occurs to the peak wavelength of radiation as the temperature of an object increases?

• It becomes longer.

• It remains the same.

• It becomes shorter.

• It disappears.

At 7,000 degrees centigrade, what is the peak wavelength of radiation emitted by an object?

• 400 nanometers

• 600 nanometers

• 700 nanometers

• 500 nanometers
