Description : What is a blackbody?
Last Answer : A blackbody is an idealized object that absorbs all electromagnetic radiation that falls on it, and emits radiation in a spectrum that depends only on its temperature, as described by Planck's law.
Description : The wavelength at which the peak of intensity of blackbody radiation Occurs – (1) increases with increase in temperature (2) decreases with increase in temperature (3) is the same at all temperatures (4) does not follow any pattern as temperature changes
Last Answer : (2) decreases with increase in temperature Explanation: According to Wien's displacement law, when the temperature of a blackbody radiator increases, the overall radiated energy increases. ... to its temperature. Shorter-wavelength (higher-frequency) light corresponds to higherenergy photons.

Description : Radiant energy emitted from a blackbody is only a function of what?
Last Answer : ANSWER: TEMPERATURE
Description : To develop the correct mathematical description of the distribution of radiated energy of a blackbody with respect to wavelength for a given temperature, Planck found it necessary to assume that the molecular ... units or quanta y) radiant energy in a continuous form z) none of the above.
Last Answer : ANSWER: X -- RADIANT ENERGY IN DISCRETE UNITS OR QUANTA
Description : The wavelength at which the peak of intensity of blackbody radiation occurs (1) increases with increase in temperature (2) decreases with increase in temperature (3) is the same at all temperatures (4) does not follow any pattern as temperature changes
Last Answer : decreases with increase in temperature
