Which of the following is a definition of steady state? select one: a, the energy used per unit time. o b. radiation that is can travel as a wave through a vacuum and which carries energy with is as it travels. this type of radiation comes in a spectrum of wavelengths and includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, x-rays and gamma rays. oc. the capacity to do work. d. the rate of energy transferred per unit area. o e. the fraction of light that reaches an object that is absorbed. f. the fraction of light that reaches an object that is passed through the object without being reflected or absorded. g. the amount of deviation between an observation and the accepted normal value of that quantity o h. the distance between crests of a wave. (units: meter) oi. the condition in which the inputs into a reservoir are equal to the outputs from the reservoir and so the size of the reservoir is not changing with time. o i. the radiation emitted by an ideal object that increases with the temperature of the object, and that is most intense at a wavelength that decreases with the temperature of the object. ok. the number of crests of a wave that passes in a unit time. (units: cycles per second). o i. the fraction of light that reaches an object that is reflected.
