How to make a prism by shifting the lens?

To make a prism by shifting the lens, follow these steps:

1. Prepare a clear glass or plastic plate to serve as the base of the prism.

2. Select a convex lens with a lens effect, place it on the glass plate, and make it perpendicular to the glass plate.

3. Place the light source on one side of the convex lens so that the light shines vertically towards the convex lens.

4. Move the convex lens so that the light passes through the center of the convex lens and creates a light spot on the other side of the glass plate.

5. Using another transparent glass plate, catch the light spot in it and move it until the light refracts as it passes through the glass plate, forming a spectrum of iridescence.

6. Rotate the glass plate that captures the spectrum, and you can see that the spectrum changes with the rotation Angle, which is the effect of the prism.

Note:

1. Be careful when operating to avoid damaging the lens and glass plate.

2. The position and intensity of the light source have an impact on the result and need to be adjusted appropriately.

3. Different types and sizes of lenses can be used to make prisms of different shapes and sizes.
