Solution
It seems like you didn't finish your question. However, based on what you've provided, I can tell you that when a beam of light composed of red and green rays is incident obliquely at a point on the face of a rectangular glass slab, the rays will refract, or bend, as they pass through the glass. This is due to a change in speed, as light travels slower in glass than in air.
The amount of bending depends on the wavelength of the light, a property known as dispersion. Red light has a longer wavelength and is refracted less than green light, which has a shorter wavelength.
So, when the light comes out on the opposite parallel face of the glass slab, the red and green rays will emerge as separate rays due to dispersion, with the green ray bending more than the red ray.
