What happens when you make a rainbow with the help of a glass of water and sunlight?

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.


What happens when light goes in or out of glass?

If it is a glass prism, the light gets split into is spectrum of colours. Normal light looks a bit like a rainbow afterwards.


A triangular glass solid that breaks down sunlight or white light into different colors is called a?

A triangular glass solid that breaks down sunlight or white light into different colors is called a prism. It works by refracting the light at different angles, causing it to split into its component colors, creating a rainbow effect.


How do you xxplain the cause of dispersion?

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.


What is the Visible?

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.

Which phenomenon is exhibited by the inclined refracting surface of a glass prism?

Dispersion phenomenon is exhibited by the triangular prism. Dispersion is splitting of composite white light into its constituent colours.


A block of glass that can split white light into different colours?

The block of glass you're referring to is likely a prism. When white light enters a prism, it is refracted, or bent, at different angles depending on its wavelength. This causes the white light to spread out into the colors of the visible spectrum, creating a rainbow effect.

What are primary colors of light?

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.


The spreading of light waves into a spectrum results from?

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.


Why do colors combined make white?

That is not true. If you are talking about all the colours of light in the spectrum coming from white light that is true. When white light passes through a glass prism, it causes the light to split into different colours because of the different angles at which they refract.
