Lesson: Infrared RadiationPhysics
In this lesson, we will learn how to describe how the temperature of an object and its surface features affect the object’s emission and absorption of infrared radiation.
Sample Question Videos
Which color of a surface makes it better at emitting and absorbing infrared radiation, black or white?
Which emits and absorbs infrared radiation more easily, a strongly reflective or a weakly reflective surface?
A plastic block is placed in constant intensity sunlight and absorbs infrared radiation. During the block’s exposure to sunlight, its temperature decreases. Which of the following statements is correct?
