cadourit reflects not only yellow light but also some greep light in addition to the light of its own colour. When these -pigments are mixed the blue will absorb the yellow light that falls upon the pixture end the yellow will absorb the bine light Both, however, will refient green light: hence the mixture annear green.
When yellow and blue 1ights are mixed, the result is volte, Thialis because they are complementary colours.

The astronomical telescope is a combination of two conver leases an objective of long focal length, and an eyepiece of short: focal length. A real, inverted image of a distant object Euch as All, is first formed by the objective lene ar A'. This image falls inside the focus of the eyepiece, which therefore, magnifies it and produces the enlarged virtual image AB. This, image, which is the one observed, is inverted relative to the object.

focal length of the eyepiece
To obtain bright images with an astronomical telescope, the objective must be large to gather as much light as possible.
