Sentences with word «radiometer»
A radiometer is a device that measures radiant energy or radiation. It consists of a small glass bulb with a rotor inside, usually with white and black blades. When exposed to light or radiation, the rotor spins faster. It helps scientists understand the intensity and properties of light or radiation. Full definition
