The air in a heat haze has a higher temperature than the surrounding air. As a result of this, the air density in a heat haze is lower than that of the surrounding air.
When light travels through air of different densities it refracts. When the refracted light shines on a wall or other surface, you perceive it as a shadow but it cannot be perceived when you look directly at it

The light is *refracted* away from its orignal path by the warmer air due to its lower index of refraction. The index of refraction for a gas is proportional to its density, which drops as it heats in accordance with the ideal gas law.

hot air moves up and the cooler air moves down and the light shining through meet different densities and bend the light.

because it`s under the window and heat defracts light.

It's an entity. It's gonna get you...
