When it leaves the glass, it is bent away from the normal, and regains the same angle as before it entered the glass. Consider the following

The NA here is a measure of the ability of the lens to gather light and resolve fine detail. The angle subtended by the lens at its focus is defined to be θ = 2 α θ = 2 α. From the figure and again using the small angle approximation, we can write

Dispersion, sometimes more specifically called chromatic dispersion , occurs when the velocities of different components of a light wave depend on the wavelengths of those components. Specific types of chromatic dispersion are defined by what causes the dependence of velocity on wavelength. service apartments near porur chennaipalpitations return precautionsWebbDispersion of light DOES occur in glass slab.

As you can see from the diagram, a smaller value of θ 2 corresponds to a larger amount of refraction because it is a larger change in angle and thus a larger change in direction of the incident light. service aprés vente auchan
