A perfect black body has its surface temperature 27 cºDetermine :Maximum radiation wavelength?Black body radiation intensity?The rate of energy released from 2m²Tungsten wire had its radiating surface area 8mm² and its temperature2100K, considering that the wire is an ideal black body, Calculate theenergy that the wire radiates in 10 minutes.Suppose the surface temperature of the Sun were about 12,000K, rather than6000K.a. How much more thermal radiation would the Sun emit?b. What would happen to the Sun's wavelength of peak emission?c. Do you think it would still be possible to have life on Earth? Explain/A The energy radiated by a black body at 2300K is found to have the maximum at awavelength 1260 nm, its emissive power being 8000W/m2. When the body is cooled to atemperature T K, the emissive power is found to decrease to 500W/m2. Find :(i) the temperature T k(ii) the wave length at which intensity of emission in maximum at the Te/ Black body becomes yellow with λ = 589 nm :a/Calculate the temperature of bodyb/Calculate the energy emitted from the body per one second where the total area is=0.031 m²/ If the intensity of radiation black body with T=3500 K, equal to maximum value atλ = 575 nm:find λ which make the intensity maximum at T=5700 K
