1 What is meant by band emission? Calculate the band emission for ëT
= 3000 ìm·K and compare your result with the corresponding value given.

2 Is it fair to say that a red rose absorbs all other colors but reflects the color red?

3 For most engineering applications, are surfaces specular reflectors or diffuse reflectors?

4 What is the unit of spectral irradiation?

5 What are the advantages of a diffuse gray surface?
