Since the filter allows only blue light to pass through, anything you see through
the filter appears either blue or black. Blue if there's any blue light coming from it,
or black if there isn't any.
blue
A green object appears black when viewed through a red filter (here a red filter means red light) because green object can only reflect green color and absorb all the other colors so in the red light it will definitely appear black.
It depends on what kind of filter, e.g. a blue filter absorbs everything except blue light, so only blue light comes out, which is why the filter looks blue, and is referred to as a "blue filter".
Red or blue. The reason a red filter looks and is red, is because only red light comes through it, and the same can be said about a blue filter allowing only blue light through. Other colors are absorbed by the dyes in the filter. If white light enters a red filter, then red light comes out, and the same goes for blue.
A cyan colored surface will reflect any blue or green light that is incident. The green filter will remove all colors of light passing through it except green. The book is illuminated with only blue light. Draw your conclusion.
It will appear as "d".
When a yellow book is viewed through a green filter, the filter will absorb most of the yellow light but allow green light to pass through. As a result, the book may appear darker and its yellow color may become less vibrant when viewed through the green filter.

Black, or nearly so. The apple reflects only green light, the red filter only lets red light through, so nothing reaches the eye.
It will be black because there may not be any green light reflecting the green apple so if theres no light then it will become black

A spectroscope is a device for producing and recording spectra for examination. When light given off by a simple burning substance is viewed through a spectroscope, a certain color will appear.
it would appear orange
Mirages are an optical illusion caused when an object is viewed through a layer of heated area, such as exists in the desert. Light rays viewed through this layer are bent and frequently appear to be a bluish patch, like an oasis, in the distance.
Green objects would appear green and red objects would appear very dark.
