The temperature of an spherical isolated black body falls from `T_(1)` and `T_(2)` in time t them time t is

The temperature of an isolated black body falls from T_(1) to T_(2) in time t. Let C be a constant, then

Choose the correct relation, when the temperature of an isolated black body falls from T_(1) to T_(2) in time 't' and assume 'c' to be a constant.

Power radiated by a black body at temperature T_(1) is P and it radiates maximum energy at a wavelength lambda_(1) . If the temperature of the black body is changed from T_(1) to T_(2) , itradiates maximum energy at a wavelength lambda_(1)//2 .The power radiated at T_(2) is

Statement-1: When the temperature of a black body is doubled from t^(@)C to 2t^(@)C , the radiant power becomes 16 times. Statement-2: The radiant power of a body is proportional to fourth power of absolute temperature.

Statement-1: When the temperature of a black body is doubled from t^(@)C to 2t^(@)C , the radiant power becomes 16 times. Statement-2: The radiant power of a body is proportional to fourth power of absolute temperature.

If temperature of ideal black body is decreased from T to T/2 than find out percentage loss in emissive rate
