White light is made up of ROYGBIV colours.
Why does a diamond sparkle?:
Reflection: When a ray of light approaches a smooth surface and the light ray bounces back, it’s called the reflection of light.
In diamonds, reflection occurs when the light hits the diamond and bounces back, giving away a glimmering shine.
Refraction: Refraction is the bending of a wave when it passes from one medium to another. The bending is caused due to the differences in density between the two substances.
Dispersion: When white light is passed through a glass prism it splits into its spectrum of colors (in order violet, indigo, blue, green, yellow, orange, and red) and this process of white light splitting into its constituent colors is termed as dispersion.
In diamond, as the light moves through the diamond, it is scattered and fractured, creating the sparkle that diamonds are known for. This is the refraction. Refraction and dispersion are the reasons why the light ray travels through the diamond. Diamond acts like a tiny complicated prism through which the light ray travels at different angles and gives a shiny appearance.
