White light from a Tungsten filiment lamp is best. If you shine a small ray of the white light in one end a rainbow ray should come out the other.
Colours shine out!
When a beam of light is shone into a triangular prism, the light is refracted (bent) as it enters the prism, then reflected internally off the prism's surfaces, and finally refracted again as it exits the prism. This interaction between the light and the prism causes the light to separate into its component colors, creating a rainbow spectrum.
The best way to play "Shine Your Light" on the recorder is to, quite simply, play "Shine Your Light" while on a recorder.
When light travels through a prism, it is bent or refracted as it passes from air into the prism and then again as it exits the prism. Different colors of light are refracted by different amounts due to their different wavelengths, causing them to separate. This separation creates a rainbow effect known as dispersion.
You may use a glass prism and shine a white light through it. You will notice that there is rainbow of colours on the wall.
When light is shone through a glass prism, the light gets refracted, or bent, at different angles depending on the wavelength of the light. This causes the light to separate into its constituent colors, creating a rainbow spectrum known as a rainbow. This phenomenon is called dispersion, and it occurs because different colors of light travel at slightly different speeds in the prism.
A prism will split light into its component colors. If a colored light is used, there will be less colors in the split light. A beam from a red light for instance will have very little blue or green light in it so you will not get the full spectrum from the prism.
When the light ray strikes the surface of the prism, both when it enters and when it leaves, it bends owing to the different in the speeds of light in air and the material of which the prism is made. The amount of bending depends in part on the frequency of the light which is related to the colour of the light, hence the appearance of a colour spectrum which can be seen from a triangular prism.
It's refracted, just as visible light is, *given* that the prism is transparent to UV. Since the angle of refraction increases with decreasing wavelength, expect UV to be refracted to a greater degree than visiblelight.
Well maybe you should try looking at Dollarama. Although trust me it is really cool when you buy a prism and shine a light on it you see a rainbow. Trust me i have done it in school it is totally cool!!
A crystalloid is anything that looks crystal like. Crystals normally take of the shape of clear light filtering substances that emit a prism of colors and shine when they are hit with light.
Depending on the positioning of the prism, it will merge the rainbow back together or spread the eight rays even further. Using this tactic, it is possible to concentrate light even further inwards, depending on how you orient the prism. If an edge is facing the light, it will spread. If a face is facing the light, it will converge.
