You are thinking of a Prism.

The phrase is "to the last drop." Referring to blood, it means " as long as life endures." In a coffee commercial, it means the last little bit in the glass or cup. The in itself insignificant little annoyance that finally makes you snap. The drop that breaks the surface tension on an overfull glass of water and makes the water overflow. See also "The straw that broke the camel's back".
possessive form of the word glass: glass'
Tempered glass can be laminated, but laminated glass cannot be tempered.
I can use the words: cheval glass, gaper, hand glass, imager, looking glass, pier glass, polished metal, reflector, seeing glass or speculum.
The sunlight hits the glass of water and then the light disperses out as a spectrum of colour (rainbow). This is because sunlight is white light and white light contains the 7 colours of the rainbow. When it hits the glass the colours refract and disperse out as the spectrum of colours, which we see as a rainbow.
A prism
If it is a glass prism, the light gets split into is spectrum of colours. Normal light looks a bit like a rainbow afterwards.
White light is made up of many lights which have different properties. We say that there are seven colours of light. We see a spectrum when white light is passed through a glass prism. When the various colours pass out of the air and into the prism, they are bent at different angles. This happens again when the rays leave the glass and pass back into the air. That is when we see the almost magical spectrum.
When composite white light with seven colours as constituents enter into triangular prism, then different colours get refracted at different angles because of the different refractive index value of glass for different colours. Refractive index is defined as the ratio of the speed of light in free space to that in the glass medium. As the speed of the different colour differ, the refractive index varies. Hence they have different angle of refraction. So all the colours have been split up. As we use a triangular prism, as the refracted colours fall on the other face of the prism, once again separation becomes possible. Hence the phenomenon of dispersion. But this will not be possible when we use a rectangular glass slab. So triangular prism is essential to have dispersion.
White light is composed of many colours. When these colours combine, they look white. One way of showing that white light is composed of different colours is to make white light pass through a glass prism. This splits up the white light into its constituent colours. I f you hold a screen in its path, you will see a band of colours. This band of colours is called the spectrum. Since it is visible to human eyes, it is called the visible spectrum.

A block of glass that can split white light into the many colors that it is comprised of is called a prism. The name comes from the traditional shape of the tool, which is a triangular prism.
Dispersion phenomenon is exhibited by the triangular prism. Dispersion is splitting of composite white light into its constituent colours.
This Q&A is about light colours. Paint colours are substances, and different from light colours.If you hold up a glass prism to a beam of sunlight, you'll see the light form a rainbow of colours. This is called the spectrum. It consists of all the colours that make up "white" light.Although you might be able to see seven colours in the spectrum, the white light is really made up of three basic colours. These are called the primary colours because they cannot be made from any other colours. The primary colours of light are red-orange, green, and violet blue. The other colours you see in spectrums or rainbows are made by a mixture of the primary colours.When the naked eye looks at the spectrum, it can see three mixed colours, which are called secondary colours. The secondary colours in light are green-blue, yellow, and magenta-red. You can produce these colours by mixing the primary colours in certain combinations.
Yes, very easily. A ray of white light can be split be shining it through a prism (triangular glass block) or a raindrop: both create a spectrum, or rainbow, of split up colours. This works because white light is made up from different colours of light that are all waves with different wavelengths/frequencies. This means that the colours are all refracted (bent) by different amounts when they go through the prism/drop, causing the ray of white light to split up into its components.
