Tyndall phenomenon tester and experimental method thereof

Abstract

The invention discloses a Tyndall phenomenon tester and an application method thereof. The tester comprises a laser light source box (1), at least one light emitter (2) and at least one group of light filtering components and a transparent container (6) for containing sol or a solution. The light filtering components comprise one group of light filters for performing light filtering on emitted laser light by selecting light filters of different colors. The light emitter (2) is connected with the laser light source box (1) for emitting laser light. The light filtering components are arranged on the transmitting end side of the light emitter (2). The laser light is filtered by the light filtering components and is incident into the transparent container (6) for tests. According to the invention, a light source is adopted to transmit light filters of complementary colours, the beam path is introduced outwards so as to change the shape, the sol adopts coloured sol, such as nanogold, etc., in the experiment, and the particularity of the Tyndall effect is disclosed.

Description

technical field [0001] The invention relates to a test appliance and an experiment method thereof, in particular to an experiment instrument and a use method of the Tyndall phenomenon of colored sol under different color light sources, and the instrument is mainly used for teaching and demonstration. Background technique [0002] When a beam of light passes through the sol, a bright "pathway" in the sol can be observed from the vertical direction of the incident light. This phenomenon is called the Tyndall phenomenon, also known as the Tyndall effect (Tyndall effect) and the Dinzel phenomenon. , Dinzel effect, can be used in the laboratory to identify sols and solutions. [0003] The light sources used in the current experiments are all different white lasers as light sources, which cannot fully demonstrate the special Tyndall phenomenon of colored sols under different color light sources, and most of the containers used in the current experiments to hold the solution are te...

AI Technical Summary

Problems solved by technology

[0003] The light sources used in the current experiments are all different white lasers as light sources, which cannot fully demonstrate the special Tyndall phenomenon of colored sols under different color light sources, and most of the containers used in the current experiments to hold the solution are test tubes or beakers for the convenience of the experiment. The limitations are relatively large. The glass test tubes specified in the teaching materials are used as experimental equipment, and some other solutions also limit certain types of containers, so the application is not very convenient.
