(A) According to Kirchhoff's law of radiation,good absorbers of a particular wavelength are also good emitters of that same wavelength.Red glass appears red because it transmits red light and absorbs green light (as red and green are complementary colors).When the red glass is heated to a high temperature and placed in a dark room,it emits the radiation it is capable of absorbing most strongly.Since red glass is a strong absorber of green light,it will emit green light strongly when heated. Therefore,it will appear green in a dark room.

When red glass is heated in a dark room,it will appear:
