Answer:
Explanation:
We shall apply Wien's displacement law which is as follows .
λ T = b where λ is wavelength of light that is coming out of hot body to maximum extent .
Putting the value of temperature given and b
λ x 500 = 2898 μmK
λ = 5.796 μm = 5796 nm
For temp 1050 K
λ = 2760 nm
For temp 1800 K
λ = 1610 nm
For temp 2500 K
λ = 1159.2 nm
The visible range starts from 740 nm .
Hence we can expect that some amount of visible light may emerge at the temperature of 2500K because the wavelength that we have calculated above gives the value of peak wavelength of a spectrum of light coming out of hot body .
