There is a rectangular pyramid, a triangular prism and a cube. They are all colorless and transparent glasses. But when they encounter the white flashlight on the phone, brilliant colors filled the room immediately. This is because the speed of the light decreases when the white light passes through the glass body with different angles, and changes the direction.
Because each colors’ light has distinct wavelengths, white light disperses into seven colors. Red light has the longest wavelength in this range of seven colors, while violet light has the shortest. In a vacuum, all colors of light travel at the same speed. However, in any transparent material, such as glass or water, various colors of light move at different rates. Various colors’ lights bend through different angles due to differences in their velocity. Red light travels the fastest through any transparent medium, whereas violet light travels the slowest.
As a result, red light bends the least while violet light bends the most. Thus, the dispersion of white light into seven colors happens when various colored photons bend at different angles while passing through a glass prism.
In addition, the dark background makes some of the angles of the vitreous look like mirrors. By the multiple refraction and reflection of these vitreous, a simple white light and a bunch of colorless glasses create a colorful and beautiful scene after imaging.
