Just after detonation, the fireball in a nuclear blast is approximately an ideal blackbody radiator with a surface temperature of about 1.0 x 107 K.
(a) Find the wavelength at which the thermal radiation is maximum
(b) Identify the type of electromagnetic wave corresponding to that wavelength. This radiation is almost immediately absorbed by the surrounding air molecules, which produces another ideal blackbody radiator with a surface temperature of about 1.0 x 105 K.
(c) Find the wavelength at which the thermal radiation is maximum
(d) Identify the type of electromagnetic wave corresponding to that wavelength.
