The power radiated by a black body is P and it radiates maximum energy at wavelength, lambda_(0) . If the temperature of the black body is now changed so that it radiates maximum energy at wavelength (3)/(4)lambda_(0) , the power radiated by it becomes nP. The value of n is

What is black body radiation ?

A negligibly small current is passed through a wire of length 15m and of uniform cross-section 6.0xx10^-7m^2 and its resistance is measured to be 5.0Omega. What is the resistivity of the material at the temperature of the experiment ?

A spherical black body of radius 12 cm radiates 450 W power at 500 K. If the radius is reduced to half and temperature is doubled. find the power- radiated in watt.

A wire of length 1 m and radius 10^(-3) m is carrying a heavy current and is assumed to radiate as a black body. At equilibrium its temperature is 900 K while that of the surroundings is 300 K. The resistivity of the material of the wire at 300 K is pi^2xx10^(-8)Omega-m and its temperature coefficient of resistance is 7.8xx10^(-3)per@_C (Stefan's constant =5.68xx10^(-8)W-m^2-K^4) . So, the current in the wire is
