Question 17

An automated inspection camera uses white light to examine two opaque plastic components. Component A reflects green and blue light and absorbs red light. Component B reflects red and blue light and absorbs green light. Before reaching the camera sensor, the reflected light passes through a filter that transmits red and green light but absorbs blue light.

Which colours are recorded by the camera from component A and component B?

[1]
A

component A: green and blue; component B: red and blue

B

component A: green only; component B: red only

C

component A: red only; component B: green only

D

component A: red and green; component B: red and green
