SUMMARY

The phenomenon of seeing car reflections on hot roads is known as a mirage. This occurs due to the refraction of light caused by temperature differences between the hot air near the ground and the cooler air above. The less dense hot air bends light upwards, creating the illusion of a reflection. Additionally, these temperature inversion layers contribute to a significant number of UFO sightings, as they can distort images at various heights above the ground.

PREREQUISITES
  • Understanding of light refraction principles
  • Basic knowledge of atmospheric layers and temperature gradients
  • Familiarity with the concept of mirages
  • Awareness of optical illusions related to heat
NEXT STEPS
  • Research the physics of light refraction
  • Explore atmospheric science related to temperature inversion
  • Study the relationship between heat and optical illusions
  • Investigate the connection between mirages and UFO sightings
USEFUL FOR

Students of physics, meteorologists, and anyone interested in optical phenomena and atmospheric science.

Why is it that on a hot day, you can see a cars reflection on the road. What is this called?
 
Science news on Phys.org
It is called a mirage. IIRC, it happens because the hot air next to the ground is less dense than the cooler air above, and so light gets refracted upwards.
 
Those inversion layers are also responsible for a high percentage of UFO reports. The image can turn up anywhere within reason, such as a hundred feet off of the ground.
