Kaleidoscope
A microscope is an optical instrument that makes small objects appear larger by using a combination of lenses to magnify the image of the object.
A magnifying glass, a microscope, or a telescope makes things larger.
A telescope helps you see from afar and a Kaleidoscope is for fun. It makes shapes and when you point it at an object, you see it in the shapes and colors in the kaleidoscope. My father got me one when I was 5 and I still have it
Magenta coloured light makes white light when mixed with green light
Newts are brightly coloured because they eat multi-colored animals which amazingly makes them super-natural!!!!
The organ is the only instrument for sacred music. Mozart described it as 'the king of instruments'.
The term is "percussion instrument" (makes sound when struck).
the bigger an instrument is, the lower the sound that it makes
Autocollimation is a setup where a beam of parallel light rays is made to leave an optical system (the system to be collimated) and is reflected back into the same system by a plane mirror (the beam should therefore end up where it stated from). One can then manually or use some mechanism ("auto"matically) to adjust the optics of the instrument being collimated so that the geometry of the instrument makes the beam reflect back to its start point.
Bassoon
It is a stringed instrument that makes music.
