Detailed Solution

When red and blue lights are incident on the glass, then the speed of the red light is greater than the blue light and blue light bends more towards the normal.

In the case of red and blue light, blue light has a shorter wavelength than red light. This means that the blue light experiences a larger change in speed and a greater bending or refraction than the red light as it enters the glass surface. This causes the blue light to bend more towards the normal than the red light.
