Diathermanous Body
A diathermanous body refers to a material or substance that allows all incident radiation to pass through it. This means that the body does not absorb or reflect the incident radiation, but rather transmits it completely.
Explanation
When radiation, such as light or heat, falls on a diathermanous body, it is not absorbed or reflected by the material. Instead, the radiation is transmitted through the body, allowing it to pass through unaffected.
Comparison with Other Options
Let's compare the given options to understand why option 'C' is the correct answer:
a) Shines as a result of incident radiation: This option suggests that a diathermanous body shines when exposed to incident radiation. However, a diathermanous body does not emit light or shine itself. It simply allows the incident radiation to pass through it.
b) Gets heated up as a result of absorption of incident radiation: This option implies that a diathermanous body absorbs the incident radiation and gets heated up. However, since a diathermanous body does not absorb the radiation, it does not get heated up as a result.
c) Allows all the incident radiation to pass through it: This option correctly describes the behavior of a diathermanous body. It allows all the incident radiation, whether it is light or heat, to pass through it without any absorption or reflection.
d) Partly absorbs and partly reflects the incident radiation: This option suggests that a diathermanous body absorbs and reflects the incident radiation. However, a diathermanous body does not absorb or reflect the radiation, but rather transmits it completely.
Conclusion
In conclusion, a diathermanous body allows all incident radiation to pass through it without any absorption or reflection. This property makes it useful in various applications, such as transparent windows, lenses, or materials used in heat transfer processes where radiation needs to be transmitted without interference.
