Presentation transcript:

Week One - Physics

Define Infrared radiation. What is a thermogram? Define the term emit. Describe the surface that is a good reflector of infrared radiation. Describe the surface that is a good absorber of infrared radiation. Why is the inside of a vacuum flask shiny? Describe how the rate of infrared emission changes with increasing temperature. Describe the necessary conditions for an object to absorb infrared radiation. Define medium. True/False - Infrared needs a medium to be able to travel through.
