Which color of light undergoes the smallest refraction when passing from air to glass?
Red light undergoes the smallest refraction when passing from air to glass due to its longer wavelength compared to other colors of light.

Why is the value of the angle of deviation for a ray of light undergoing refraction through a glass prism different for different colour of light?
Different colors of light have different wavelengths, which results in different speeds of light in the prism. This leads to varying amounts of bending or refraction for each color, causing variations in the angle of deviation. This is known as dispersion.
What role does the passing down of traits through DNA have on families and the characteristics they share?
The role that the passing down of traits through DNA have on families, and the characteristics they share is physical appearance such as; height, skin color, hair color, and eye color.
What phenomenon causes colors of visible light to be seperated by a prism?
Under a physical point of view, pure colors are different frequencies in the light. Generally a light beam is composed by a set of frequencies each of which with a different intensity. If a very concentrated pack of frequencies is clearly more powerful that color dominates and you see a colored light, otherwise you see a combination of colors that tends to white as far as the light spectrum (the set of present frequencies) is wide and all the frequencies have the same intensity. The refraction index of a material (glass for example) is a function of the frequency of the incoming light. Since the angle of refraction of a light beam by passing through the interface between different media depends on the two refraction indexes, beams of different frequencies are deflected at different angles by passing through the two interfaces air-glass and glass-air they encounter are deflected at different angles. If a light beam comprises a large number of frequencies, passing through the prism each frequency is deflected to its own angle. Thus the frequencies are divided and exits from the prism as different beams. The global effect is that a white beam (all the frequencies are present) exists from a prism as a sort of rainbow, where the colors (different frequencies) are directed in different direction and thus divided.
Which color of light passing from glass to air has minimum critical angle?
The color of light that has the minimum critical angle when passing from glass to air is red. This is because red light has the longest wavelength of all the visible colors, which leads to a smaller change in speed and a larger angle of refraction at the interface between the two mediums.
Which color of light undergoes the smallest refraction when passing from air to glass?
Red light undergoes the smallest refraction when passing from air to glass due to its longer wavelength compared to other colors of light.
What is Snell's law?
it states that the ratio of sine of angle of incidence/sine of angle of refraction=constant, for the light of given color and given pair of medium. where n1 and n2 are the indices of refraction of light in different materials.
What color results from the greatest refraction?
Violet results from the greatest refraction as it has the shortest wavelength among visible colors, causing it to bend the most when passing through a medium like a prism.
What word describes the bending of light as it enters and leaves a prisam?
When light traverse the interface between two transparent material with a different refraction index it undergo refraction, that is the angle of incidence on the interface is different from the angle with which the light comes out from the surface itself. In a prism refraction happens as the light passes from air to the prism material (generally glass or a polymer like PMMA, also called Plexiglas) and when the light leaves the prism, passing from it to air again. Since the difference of incident and emerging angles is opposite passing from air to prism and from prism to air (let us call that angle q) the total diffraction angle due to the passage through a prism is 2 q. Since q depends on the light wavelength (that is on the light color) different colors are diffracted at different angles and the light at the prism output appears as decomposed in different rays, exiting from the prism with different angles, one for each color. Doping the prism glass with impurities increasing a lot its refraction index, complete refraction can be obtained for selected light colors. These colors at the first interface with the prism have a refraction angle greater than 90° and light of those colors does not enter into the prism. Thus colors suffering total refractions lack from the prism output light.
What do rainbows get color from?
White light is a mixture of all the colors of the rainbow. When white light passes through raindrops refraction occurs; it changes direction - we see colors because the amount of refraction depends on the frequency (ie the color) of the light passing through the water - this process is called dispersion.

When light passes through a prism which color of light is reflected the most?
When light passes through a prism, the color that is reflected the most depends on the properties of the prism and the angle at which the light enters. Generally, all colors of light are refracted to different degrees by the prism, with each color having a different wavelength and therefore a different angle of refraction.
In visible light color is an indicator of what?
Refraction
When a ray of light enters water from air then?
Light will undergo refraction, and the light rays will bend towards the normal, because it is entering an optically denser medium. In this case, the angle of refraction will be smaller than the angle of incidence. In addition, the speed of light will be reduced when travelling in water.
How long are rainbows?
A rainbow has no length- it is a refraction of light, dependent on the angle between the viewer and the light source. When seen from an airplane, it may be a circle of color, and not a "bow".
Does the angle of minimum deviation depend upon the colour of light used?
Yes, the angle of minimum deviation does depend on the color of light used. This is because different colors of light have different wavelengths, which can lead to variations in how light is refracted when passing through a prism, causing the angle of minimum deviation to differ for each color.
