Answer is Right!
Answer is Wrong!
The correct answer is: B. Temperature
A bolometer is a device used to measure the radiant power of electromagnetic radiation. It is a type of radiometer that uses the change in resistance of a material to measure the amount of radiation absorbed. The resistance of a material changes with temperature, so the bolometer can be used to measure the temperature of a source of radiation.
The other options are incorrect. Frequency is a measure of how often a wave oscillates,
