The device is a glass prism. A cross-section of a prism is an isosceles triangle.
white light can be split into the colours of the rainbow
Light appears white, however it is made up of different colours, which when put together make white light. These colours can be seen if you direct light through a prism. At the right angle the light is split up into the colours (rainbow).
white light can be split into the colours of the rainbow
the answer is a (prism).
Use a prism.
A prism is an object that can be used to split white light into its different colors by refracting the light at different angles due to their different wavelengths.
Shining a white light through a glass prism will split the light into rainbow colours.
The name for when light is split up into the different colors of the spectrum is called "dispersion."
The violet (higher frequency) light.
White light can be split up into lots of different coloured light waves using a prism. We call this range of colours the visible spectrum.
A prism is a device that can split light by refracting it at different angles depending on the wavelength of the light. This separation of colors is known as dispersion.
