The higher the temperature of an object, the ____________________. A) Neither of these.B) shorter the wavelengths of radiation it emits.C) higher the frequencies of radiation it emits.D) Both of these.
The correct answer is D) Both of these.
When an object's temperature increases, it affects the behavior of its atoms and molecules. As a result, the object emits electromagnetic radiation in the form of heat. This radiation consists of various wavelengths and frequencies.
Firstly, the higher the temperature of an object, the shorter the wavelengths of radiation it emits. This is known as Wien's law, which states that the wavelength of maximum intensity emitted by a black body (an idealized object that absorbs all radiation incident on it) is inversely proportional to its temperature. In simpler terms, as the temperature of an object increases, the peak wavelength of its emitted radiation shifts towards shorter wavelengths.
Secondly, the higher the temperature of an object, the higher the frequencies of radiation it emits. The frequency of radiation is directly related to the energy of the emitted photons. According to Planck's law, the energy of the photons emitted by an object is directly proportional to its temperature. Therefore, as the temperature increases, the frequency of the emitted radiation also increases.
So, in conclusion, the higher the temperature of an object, both the wavelengths and frequencies of the radiation it emits increase.
