Which parts of Earth are emitting radiation?

Rate the intensity of radiation emitted by each continent from lowest to highest (roughly).

Rate the frequency of radiation emitted by each continent from lowest to highest (roughly).

Which side of Earth emits radiation?

Which side of Earth emits the most radiation?

Which side of Earth emits radiation with the longest wavelength?

Which emits the highest frequency radiation – Earth or the sun?

Dr. Rowley categorized radiation according to its wavelength Dr. Rowley categorized radiation according to its wavelength. Which category is absorbed by molecules?

What percent of the radiation reflected by Earth’s surface is then absorbed by the atmosphere?

If my body emits 90 J of radiation every minute, how much power (in Watts) am I emitting?

What is the mathematical relationship between absorbed energy and the change in temperature of the absorbing object?

A meter placed 10 inches from a certain light bulb measures a power of 20W coming from the bulb. If the meter is moved to a position 100 inches away from the bulb, what power will it measure?

A particular object at 100 K emits 1 W of radiation A particular object at 100 K emits 1 W of radiation. If the temperature of that object were raised to 200 K, how much radiation will it emit?
