Radiometer

The name Radiometer is frequently used to refer to a Crookes radiometer (light-mill) This is an early device wherein a rotor in a partial vacuum spins when exposed to light The Nichols radiometer is a newer and more sensitive radiometer than the Crookes type It measures radiation pressure It has two small mirrors suspended on a quartz fiber Get price

Radiometer

The term radiometer is often used to refer specifically to a type of thermal detector invented by Sir William Crookes (c 1874) Because his device was somewhat insensitive and not readily calibrated it is rarely used today as a scientific instrument A Crookes radiometer consists essentially of two parts Get price

About Crookes radiometer

The Crookes radiometer also known as a light mill consists of an airtight glass bulb containing a partial vacuum Inside are a set of vanes which are mounted on a spindle The vanes rotate when exposed to light with faster rotation for more intense light providing a quantitative measurement of electromagnetic radiation intensity Get price

Come One Come All! Explore the Effect

28-7-2017Crookes' original explanation for the motion of the radiometer was that the light was exerting more pressure on the dark side of each vane than on the light side But this radiation pressure explanation was ruled out by the discovery that if more of the remaining air molecules were removed from the bulb creating a better vacuum the motion ceased Get price
