undefined video tutorial00:11:02
Find the wavelength at which a black body radiates maximum energy, if its remperature is
(Wein’s constant b = 2.898x 10-3 mK)
(A) `0.0414 xx 10^-6`
(B) `4.14xx10^-6 m`
(C) `41.4 xx10^-6m`
(D) `414 xx10^-6m`
The wavelength range of thermal radiation is
(A) from 4000 Å to 7000 Å
(B) from 7700 Å to 4 x 106 Å
(C) from 106 Å to 108 Å
(D) from 4 x 10-12 Å to 4 x 108 Å
When electron in hydrogen atom jumps from second orbit to first orbit, the wavelength of radiation emitted is λ. When electron jumps from third orbit to first orbit, the wavelength of emitted radiation would be _______.
