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. The reason for the rotation was a cause of much scientific debate in the ten years following the invention of the device, but in 1879 the currently accepted explanation for the rotation was published. Today the device is mainly used in physics education as a demonstration of a heat engine run by light energy. It was invented in 1873 by the chemist Sir William Crookes as the by-product of some chemical research. In the course of very accurate quantitative chemical work, he was weighing samples in a partially evacuated chamber to reduce the effect of air currents, and noticed the weighings were disturbed when sunlight shone on the balance. Investigating this effect, he created the device named after him. It is still manufactured and sold as an educational aid or curiosity. 发送询价 联系人：* 邮箱：* 电话： 内容：* 验证码：* (所有 * 星号必填) [ 上一页：CR-60110GRT ] [ 下一页：CR-60110AMT ] 相关产品 光压风车,克鲁克斯辐射计, Radiometer CR-T60190TBLT (Twisted Base) 光压风车,克鲁克斯辐射计, 热能物理实验器材, Crookes Radiometer CR-O60100AM 光压风车,克鲁克斯辐射计, 热能物理实验器材, Crookes Radiometer CR-60110TBLT 光压风车,克鲁克斯辐射计,Radiometer CR-T60190TGRT (Twisted Base) 光压风车,克鲁克斯辐射计, 热能物理实验器材, Crookes Radiometer CR-O60100BL 光压风车,克鲁克斯辐射计, 热能物理实验器材, Crookes Radiometer CR-60110TGR 光压风车,克鲁克斯辐射计Radiometer CR-060, 080,100T 光压风车,克鲁克斯辐射计,Radiometer CR-T90245T (Twisted Base)
