A perfectly black bodya)Absorbs all the incident radiationb)Allow all ...
Explanation:
Perfectly Black Body:
A perfectly black body refers to an object that absorbs all incident radiation without reflecting or transmitting any of it.
Absorption of Incident Radiation:
- A perfectly black body absorbs all incident radiation that falls on its surface.
- This absorption occurs because the black body is an ideal absorber, meaning it captures all wavelengths of radiation that hit it.
Key Points:
- The black body does not reflect any radiation, which is why it appears perfectly black.
- The surface of a perfectly black body is typically coated with lamp black or graphite to enhance its absorption properties.
- This property of absorbing all incident radiation is essential in various scientific and engineering applications, such as in thermal radiation studies and in the design of blackbody radiation sources.
Therefore, the correct answer is option 'A' - a perfectly black body absorbs all the incident radiation that falls on it.
