Inferring from the infrared image, the temperature of the top of the radiator is approximately:

The frequency of infrared radiation detected from an object is 8 × 1012 Hz.  What is the temperature of the object?  (Note:  For the speed of light, use 3 × 108 m/s.)A.80 °CB.50 °CC.30 °CD.10 °

The human eye is most sensitive to 560 nm (green) light. What is the temperature (K) of a black body that would radiate most intensely at this wavelength?

In which region of the electromagnetic spectrum do objects at room temperature radiate the most?

This infrared image shows a hand pointing to a switch on a power board. The colours represent the amount of infrared radiation being emitted, as shown by the scale on the right hand side.Identify which statement is true. The hand is emitting the least radiationThe hottest part of the image is the background, shown in dark blueThe switch at point D is emitting the most radiationThe plug at point B is emitting the least radiation

Amal is carrying out an experiment investigating which colours are the best absorbers of infra red radiation.
