Final answer:
The statement is false because all objects at any temperature can emit infrared radiation, with colder objects emitting lower intensities and warmer objects emitting more intense radiation along with visible light at higher temperatures.
Step-by-step explanation:
The statement that 'Only objects above 0°C can emit infrared radiation' is false. Infrared radiation is emitted by all objects, regardless of their temperature, as a form of electromagnetic radiation that corresponds with the heat being emitted by an object. Even objects at temperatures below 0°C, such as ice or cold celestial bodies, can emit infrared radiation, albeit at lower intensities compared to hotter objects.
The amount of infrared radiation and the peak wavelength at which it is emitted are both related to the object's temperature according to the Stefan-Boltzmann law and Wien's law. A burner on a stove, for instance, emits infrared when it is at a low setting and not visible to the human eye, and it emits light at higher frequencies, visible to the human eye, when it is set to a higher temperature.
This phenomenon demonstrates that the energy and visibility of radiation increase with temperature, and objects can emit a full spectrum of electromagnetic radiation at any temperature. Hence, it is not true that only objects above 0°C can emit infrared radiation.
