A black body at 20000 K, emits maximum energy at a wavelength of `1.56 mu m`. At what temperature will it emit maximum energy at a wavelength of `1.8 mu m` ? |
|
Answer» Correct Answer - `[1733 K]` Here, `T_(1)=2000 K, lambda_(1)=1.56 mu m`, `T_(2)=?, lambda_(2)=1.8 mu m` `lambda_(1) T_(1)=lambda_(2)T_(2)` or `T_(2)=(lambda_(1)T_(1))/(lambda_(2))=(1.56xx2000)/(1.8)=1733 K` |
