Answer 1

The primary color that must be added to cyan light to produce white light is red.

Step-by-step explanation:

The primary color that must be added to cyan light to produce white light is red.

In the additive color system, red, green, and blue are the primary colors. When all three colors are combined at full intensity, they create white light. By adding red light to cyan light (which is a shade of blue-green), the missing red component is added and white light is produced.
