How is a rainbow similar to prism?
Rainbow is not similar to prism. A rainbow is an optical and meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. A prism is a transparent optical element with flat, polished surfaces that refract light with at least two of the flat surfaces having an angle between them. A dispersive prism can be used to break light up into its constituent spectral colors (the colors of the...

Do high frequency waves move faster than low frequency waves?
The answer depends on the medium in which the wave is traveling. If the medium is non-dispersive, all frequencies will travel at the same speed (the group delay and phase delay will be the same). If the wave is traveling in a dispersive medium, the frequency of the wave will affect the speed (and the group delay and phase delay will not be the same). The type of dispersive medium also determines whether high frequency waves will travel faster or slower than...

Why does red light travel faster than blue light in air?
In a normal dispersive medium, red light is farthest from the base of the prism and blue light is the closest. Red travels faster. ...

Which instrument has been used to break up light into rainbow like bands of color?
A dispersive prism is used to break up light into its constituent spectral colors. See: Wikipedia http://en.wikipedia.org/wiki/Prism_(optics) ...
Why must the slit width of a prism monochromator be varied to provide constant effective bandwidths but a nearly constant slit width provides cnstant bandwidth with a grating monochromator?
Prisms and gratings have different dispersive properties. Grating has a linear dispersion of wavelengths meaning the band on the focal plane varies linearly with the wavelength. Prisms are not linear, the shorter the wavelength the greater the dispersion. Thus, when a spectrum is being scanned, the dispersive device needs to rotates different amounts depending on whether it is prism or grating to focus light on the exit slit. If its grating, the slit width will need to be varied minimally; if it...

Why glass is better than fused silica as a prism construction material for a monochromator to be used in a region of 400 to 800 nm?
Fused silica is used for ultraviolet radiation. For the visible spectrum some types of glasses are more dispersive - this means that the refractive index is more dependent on the wavelength of a radiation. ...
