Consider a black body of surface area 28.0 cm2 and temperature 5600 K.
(a) How much power does it radiate?
(b) At what wavelength does it radiate most intensely?
(c) Find the spectral power per wavelength at this wavelength.
(d) 5.00 nm (ultraviolet light or an x-ray)
(e) 400 nm (at the boundary between UV and visible light)
(f) 700 nm (at the boundary between visible and infrared light)
(g) 1.00 mm (infrared light or a microwave)
(h) 10.0 cm (a microwave or radio wave)
(i) About how much power does the object radiate as visible light?
