What is the refractive index of a rectanguler glass block?
The refractive index of a rectangular glass block depends on the type of glass used. However, common values for the refractive index of glass are around 1.5 to 1.7. This value indicates how much light is bent or refracted as it passes through the glass block.
Why dispersion do not take place through glass slab?
Dispersion does not occur in a glass slab because the different colors of light all travel at the same speed in the glass medium. Since dispersion is the phenomenon where different colors of light travel at different speeds, it does not occur when light passes through a homogeneous medium like a glass slab.
What happens when light is shone at glass prism?
When light is shone at a glass prism, the light is refracted (bent) as it enters the prism, then it undergoes dispersion where the different colors of light are separated due to their different wavelengths. Lastly, the light is refracted again as it exits the prism, producing a spectrum of colors known as a rainbow.
When white light travels through a glass prism which colour is refracted through the largest angle?
Violet light is refracted through the largest angle when white light passes through a glass prism because it has the shortest wavelength of all the colors in the visible spectrum.
When is light refracted?
Light is refracted when it passes from one medium to another with a different optical density, such as from air to water or from air to glass. This phenomenon causes the light to change direction as it enters the new medium due to a change in its speed.

How do you xxplain the cause of dispersion?
When composite white light with seven colours as constituents enter into triangular prism, then different colours get refracted at different angles because of the different refractive index value of glass for different colours. Refractive index is defined as the ratio of the speed of light in free space to that in the glass medium. As the speed of the different colour differ, the refractive index varies. Hence they have different angle of refraction. So all the colours have been split up. As we use a triangular prism, as the refracted colours fall on the other face of the prism, once again separation becomes possible. Hence the phenomenon of dispersion. But this will not be possible when we use a rectangular glass slab. So triangular prism is essential to have dispersion.
What do you have to do for Refraction through a rectangular glass block?
when a parallel beam hit the rectangular glass it will gave a refraction.

When light goes through a glass window the light is primarily?
When light goes through a glass window, it is primarily transmitted, refracted, and reflected. Glass allows most of the light to pass through (transmitted), while some of the light can be bent (refracted) as it enters and exits the glass. Additionally, a small portion of the light can be reflected off the surface of the glass.
A block of glass that can split white light into different colors?
The block of glass is likely a prism. When white light passes through a prism, it is refracted (bent) at different angles based on its wavelength, causing it to separate into its component colors, creating a rainbow effect. This phenomena is known as dispersion.
What block of glass can split white light into different colours?
A prism made of glass can split white light into different colors through a process called dispersion. When light enters the prism, it is refracted and separated into its component colors due to their differing wavelengths, resulting in a spectrum of colors.
What happens when light is refracted through glass?
The light will bend into an angle because of the shape of the glass and the location from which the light is coming from.
Can a glass slab bend different coloured lights by different amounts?
Yes, a glass slab can bend different colored lights by different amounts due to the phenomenon of dispersion, where light of different colors is refracted by different angles, resulting in a separation of colors. This is why we see rainbows when light passes through raindrops or a prism.
