the answer is a (prism).
Its a spectrum
Refraction is the name for what happens when light is split up into the different colors of the spectrum.
This phenomenon is called dispersion, where light is separated into its component colors due to differences in their wavelengths.
This phenomenon is called dispersion. It occurs when light waves pass through a medium and are separated into different colors due to their different wavelengths.
Rain droplets can refract light. Different colours refract in different amounts so a spectrum is produced.
The name for when light is split up into the different colors of the spectrum is called "dispersion."
Light is made up of different colors that are a part of the electromagnetic spectrum. Different colors have different wavelengths, and when white light is separated, it can be seen as a spectrum of colors ranging from red to violet.
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 all seven colors of the spectrum combine together, they create white light. This is because white light is a combination of all the colors in the visible spectrum.
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 causes white light to separate into a spectrum because light of different wavelengths (colors) travels at different speeds inside the prism. This difference in speed causes the light to refract at different angles, resulting in the separation of the colors of the spectrum.
Different wavelengths of light have different colours, the spectrum of visible light goes from 700 nanometres to 400 nanometres and goes from red to violet. The colours are red, orange, yellow, green, blue, indigo and violet.
