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).

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.
Shining a white light through a glass prism will split the light into rainbow colours.
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.
The violet (higher frequency) light.
The range of colors that white light can be split into is called the visible spectrum. It consists of colors such as red, orange, yellow, green, blue, indigo, and violet.
Isaac newton was the first one to split white light into its colours using a glass block !
There is an infinite number of colours and shades in white light, so the colours are most commonly given as RED, ORANGE, YELLOW, GREEN, BLUE, INDIGO and VIOLET.
