The atmosphere is made up of layers of different optical densities. The deviation of light or other electromagnetic waves from a straight line as it passes through the atmosphere is known as atmospheric refraction. The star twinkles due to atmospheric refraction of starlight.
Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height. This refraction is due to the velocity of light through air decreasing with increased density.
