What do you see on holding a CD in the sun ?

Answer:
Hi there,
the surface of the CD is reflecting. So when white light falls on the surface of the metal, it reflects and forms angles of interference with the metal ridges in the CD surface and reflect in the form of a rainbow that consists of different colors. you must place a white paper in front where the image would be formed.
I hope the answer was helpful.
Thanks for asking.
Answer:
Hello thank-you for asking this question.
When you hold a CD under the sunlight it reflects a rainbow due to it's reflecting nature.
The reflecting colors that can be seen from a CD are interference colors, for example the shifting colors that we see on a soap bubble. It can be thought of as light being made up of waves, like the waves in the ocean. When light waves reflect off the ridges on your CD, they overlap and interfere with each other creating a rainbow effect.
