中三物理-輻射

1.試解釋物體表面怎樣影響它吸收和發出輻射？

A shiny surface (光滑表面) is a bad emitter and absorber of radiation. A black surface is a good emitter and absorber of radiation.

2.試解釋物體表面的溫度會否影響發出輻射的快慢？

The higher the temperature of the object, the more intense is the radiation emitted. The peak of maximum intensity of the emitted radiation shifts towards lower wavelength (波長).
