Check the wiring to the seat belt anchors. I would suspect you will find a wire loose, broken, or unhooked.
Yes. The separation of the different colors is an effect on the different colors of light called Dispersion. Dispersion simply means that light of different colors travels through the glass at different rates of speed. The rate of speed that a color of light travels through the glass also determines at what angle it is bent as it transitions from the air and into the glass. On the Pink Floyd album cover, it shows red traveling the fastest in the glass, which produces the smallest change in angle between the incident "white" light and the separated colors. Blue travels the slowest of the visible colors and therefore makes the largest bend when it enters the glass prism. Each color propagates across the glass prism and the light is then bent again as it exits the glass. The angle is again dependent upon the speed that the color of light travels inside the glass. In the air there is no dispersion of visible light that can be observed by eye under normal conditions. That means that all the colors travel at the same speed in air.

The colors of the rainbow are made when light passes through a prism - what we call "light" is actually made of many colors. The main colors of a rainbow are Red, Orange, Yellow, Green, Indigo, and Violet or Purple.
Light, as we recall from Einstein's Theory of Relativity, always travels in a vacuum at a constant speed known as c (approximately 300,000 kilometers per second) BUT light also travels at slower speeds when it is not in a vacuum (which is perfectly logical because light interacts with the media through which it passes). And light of different wavelengths will be slowed to different degrees, and consequently, it is also refracted (bent) to different degrees when passing through a prism. Hence, the wavelengths, which determine the colors, separate.
Our modern understanding of light and color begins with Isaac Newton (1642-1726) and a series of experiments that he publishes in 1672. He is the first to understand the rainbow - he refracts white light with a prism, resolving it into its component colors: red, orange, yellow, green, blue and violet. Light is electromagnetic energy that travels in waves and has frequencies both visible and invisible to the human eye. The visible light range is known as the ultraviolet (UV) spectrum. To the naked eye, UV light appears white, but it is actually made up of several different wavelengths of color. These colors are arranged in order from shortest to longest and blend from one to the next, like a rainbow. The order of the wavelengths are violet, blue and green, yellow, orange and red -- which means violet has the shortest wavelength; and red, the longest
Net of the Triangular Prism
the prism can obtained coloured of light in prism due to disperion of light
When ordinary visible light shines on a prism.
because when light hits the prism the prism scatters the light in all directions there for you can see the rainbow
I believe that you are talking about a prism, and the process where the light is broken up in to its constituent parts is called dispersion
It is named after the type of prism used in the instrument. A constant deviation prism has the property that the angle between light entering the prism (the incident light) and light exiting the prism (the emergent light) is always the same, no matter what the angle of the incident light to the prism.
As the light passes through the prism, the resulting effect is called a 'refraction'. In other words, the light enters from one side of the prism and is then 'redirected' at a right angle as it exits the prism.
red light is monochromatic light and if it shines on a prism its still red light pass through the prism, not 'rainbow' color.
A device for separating light into different colors is know as a ?
reflection
Light could bend when it enters a prism. A prism is a transparent object such as glass.
The refractive index of violet light is most in a glass prism and is the least for the red light. So violet light is most refracted in the glass prism.
Light is refracted and reflected by a (glass) prism Light is refracted and reflected by a raindrop
