Small experimental process of making rainbow

To do the rainbow experiment, you can use two simple methods, mirror or water, to complete the experiment on a sunny day.

First prepare a basin of clear water, put the mirror into the water obliquely, and then adjust the angle to reflect the sunlight to the wall. When the sunlight passes through the mirror and the water, it will disperse and form a rainbow.

2. First, turn your back to the sun and spray mist forward with a watering can. When sunlight is refracted and reflected in spherical water droplets, it will also be dispersed. Pay attention to the rainbow.

Note: A normal and beautiful rainbow can only be made on a sunny day.

In fact, rainbows are very common in our lives. On a sunny day, we stood by and waited by the road. When the sprinkler passes by, we can also see the beautiful rainbow.
