A tungsten filament of a glowing lightbulb has atemperature of approximately 203

Question

A tungsten filament of a glowing lightbulb has atemperature of approximately 2030 K. (a) Assuming the operating filament is ablackbody, determine the peak wavelength of its emitted radiationat this temperature.
1 m

(b) Why does your answer to part (a) suggest that more energy froma lightbulb goes into heat than into light?

Explanation / Answer

(a)   wavelength =   0.002898 /T =    0.002898 / 2030   = .         =    1.43 x10-6 m . (b)   thepeak wavelength is in the infrared region
