# Can a glass slab disperse light if not why?

## Can a glass slab disperse light if not why?

The dispersion occurs in prism but not in glass slab because of the geometric design. In a slab, the opposite sides are parallel to each other whereas, in the case of the prism, the sides are not parallel to each other. They travel a very small distance in the glass slab to meet the second interface.

What happens when monochromatic light passes through a glass slab?

In glass prism, the direction of the incident ray and the emergent ray of light is not parallel to each other. When a narrow beam of monochromatic light passes through: Glass slab: It deviates from the actual path but the direction of the incident ray and the emergent ray of light are parallel to each other.

What happens when a narrow beam of a monochromatic light and white light passes through a glass slab and B glass prism?

When a narrow beam of monochromatic light passes through : The direction of incident ray and emergent ray of light are parallel to each other. (b) Glass prism, it splits into its constituent seven colour. The direction of incident ray and emergent ray of light are not parallel to each other.

### What happens when a beam of white light passes through a glass prism?

When light passes through a prism the light bends. As a result, the different colors that make up white light become separated. This happens because each color has a particular wavelength and each wavelength bends at a different angle.

What happens when a narrow beam of a monochromatic light and white light passes through 3m a glass slab and B glass prism?

Answer: if white light passes through a glass prism then the light splits into different colours or rainbow colours. and if it is passed through a glass slab the light as well as the colours in it bends.

What is the difference between the refraction from a glass slab and that from a prism?

After refraction at two parallel faces of a glass slab, the ray of light emerges in a direction parallel to the incident ray on the slab. whereas in a prism a ray of light suffers two refractions on passing through a prism and hence deviates through a certain angle from its original path.

## What is monochromatic light?

Monochromatic light is light (optical radiation) where the optical spectrum contains only a single optical frequency. Light sources can also be called monochromatic, if they emit monochromatic light.
