A prism?
You are thinking of a Prism.
False. Glass is transparent and allows light to pass through, while paper is opaque and reflects more light.
A prism is a piece of glass that refracts light by separating it into its component colors.
the light rays hit the piece of glass and the surface of the glass causes it to refract
yes get a piece of glass or crystal and hold it in the sunlight. get the right angle so you can see a rainbow inside the glass/ crystal. it shows how light is actually all colours of the rainbow, however you can only see what it reflects.
A prism is a piece of glass that can split light into its different colors through refraction.
The color of light that is transmitted through a piece of red glass is red.
Non-luminous objects are those that do not emit their own light but can reflect light from other sources. Examples include the Moon, which reflects sunlight; a rock, which absorbs and reflects ambient light; a tree, which appears visible due to surrounding light; a piece of furniture, which reflects light in a room; and a glass of water, which can refract light but does not produce its own.
A prism is a triangle-shaped piece of glass that is able to bend light by refracting and dispersing the light into its component colors.
When light passes through a flat piece of glass, like a window, the light is refracted at both surfaces, but the exiting ray of light is parallel to the entering ray and hence the light's path is not really changed.
