Question

1. You stand outside on a beautifully sunny day and see an ice cream truck with bright magenta

   writing on it. Draw what is happening, starting with sunlight and ending at your eye, for you

   to see this magenta writing.

2. The side of the ice cream truck is painted bright cyan. You look at the truck through a yellow

   filter. What color does the truck appear to be? Draw what is happening, starting with sunlight and ending at your eye, for you to see this.

Answer 1

The sunlight is composed of white light which is a mixture of all colors. When the sunlight hits the ice cream truck, all the other light rays are absorbed by the writing on the truck and only magenta colored rays are reflected back from the writing which then hits our eye and we see the writing in magenta color.

A color filter is used to absorb the light colors passing through it.

A yellow filter paper will absorb all lights except yellow color. Thus the cyan color rays coming out of the truck will be absorbed by the filter and only yellow color rays will hit our eye thus truck will appear kind of yellowish.
