Why does an object reflect some colours only and absorb the rest?
The pigments used absorb some wavelengths of light and reflects the rest back to your eyes.
What object separates white light into the colors that make it up?
An object that is used primarily to split white light into its seperate color spectra is called a "prism," a triangular cross-sectioned piece of solid clear material such as glass.
Is a prism used to turn white light into black light?
No. It is used to split white light into its separate colors.
Why red light is used as the traffic light?
red light is used in traffic lights because red light has a "longer wavelength" than other colours
Which object is used to focus light in a light microscope?
Adjustment knobs are used to focus light in a light microscope.
What is the name of the device used to split up white light into its various colours?
prism

i dont even think light can be split up i dont know

The wavelength of light used to observe an object must be ... than the object itself?
The wavelength of light used to observe an object must be shorter than the size of the object itself.
What object is used to light in a light microscope?
Lens

red light is used in traffic lights because red light has a "longer wavelength" than other colours
Which colors are most commonly used in cubism works?
the colours that are normally used are very light colours because the reflection makes it look more cubism.
Which object is used to focus light in a light microscope?
Adjustment knobs are used to focus light in a light microscope.
What can b used to disperse white light into the 7 colours of the rainbow?
A prism.
What must happen to all wave lengths of light for a substance to appear white?
The colours we see in an object are only the colours that are reflected. Inferentially, the other colours are absorbed. The grass is green (when illuminated by a white light source) because the redder end of the spectrum is absorbed and used by the plant to do its stuff - photosynthesis and so on. A white card appears white because all the light wavelengths [to which we can respond] are reflected. That card may absorb some of the white light, but not at wavelengths to which we respond.
