A narrow beam of light passes through a slab obliquely and is then received by an eye (figure 18-Q1). The index of refraction of the material in the slab fluctuates slowly with time. How will it appear to the eye? The twinkling of stars has a similar explanation.

Explanation:

When the refraction index increases μ the refracted rays in the slab change their course.
That means they emerge at different points from the slab.
It results in the change of the source picture and the eye discovers that the source disappears/shifts a little over time, and the source appears twinkling like a star.

Refractive index:- Refractive index, furthermore called refraction index, measures the bending of a ray of light as it travels from one medium to another. ... Furthermore, the refractive index is equal to the speed of light c of a given wavelength in empty space separated into a material by its velocity v, or n = c/v
