| Experimental components |
Laser pen, transparent tank, soapy water |
| Experimental process | (1)Add soapy water to the tank (2)Shine a laser pen on the soapy water in the tank |
| Experimental phenomena | The result is that the light travels in a straight line in the air; when it enters the soapy water from the air, the direction of propagation will refract, and in the soapy water, the path of light is another straight line. |
| Experimental conclusion | We can draw two conclusions from this experiment: 1.In the real physical world, light travels in a straight line in a uniform medium 2.When light enters from one medium to another, refraction occurs in the direction of propagation |
| Additional analysis | Since we need to verify that light travels in a straight line in the same uniform medium and that refraction occurs when it propagates between different media, we must observe the part of light propagating in the air. The reason why soapy water is used instead of clear tap water is that the observation effect is more obvious in translucent turbid liquids. In addition, this experimental setup can also verify that different media and liquids of different densities cause light to refract at different angles by reading the angle of refraction of light. |
