Abstract

An experimental device and experimental method for the light concentration effect of cold flow in a liquid. A transparent water tank filled with water is arranged on the base, a coordinate paper is arranged on the right outer surface of the transparent water tank, and a semiconductor refrigeration device is arranged on the rear base outside the transparent water tank. Two semi-conductor cooling chips immersed in water are arranged on the semiconductor cooling chip bracket. The vertical center planes of the two semiconductor cooling chips are parallel, and the opposite surface is a cold surface perpendicular to the horizontal plane. On the left side outside the transparent water tank on the base A laser bracket with two semiconductor lasers is installed. The two laser beams emitted by the two semiconductor lasers are parallel in the same horizontal plane and are respectively located in the vertical center plane of the two semiconductor refrigerating plates. 5-10mm of the surface passes horizontally and parallelly, and is projected on the coordinate paper of the opposite side wall.

Description

technical field [0001] The invention belongs to the technical field of optical experiment teaching instruments, and in particular relates to an experimental device for light concentrating effect of cold flow in liquid. Background technique [0002] The formation of the concept of straight-line propagation of light begins with people's intuitive feelings and the "axiom" concept of straight-line propagation of light established in elementary and middle school geometric optics. In fact, the linear propagation of light is conditional, that is, it can only propagate in a straight line in a homogeneous medium, that is to say, when light is transmitted in a non-uniform medium, there may be a phenomenon of curved transmission. In nature, the bending phenomenon of light when it is transmitted in space is directly related to the distribution field of space temperature. This has long been concluded in academia, that is, due to the uneven temperature field in the atmosphere, the uneven ...
