NATURE'S OPTICAL ILLLUSIONS: AMAZING TRICKS OF LIGHT AND COLOUR

The optical illusions found in nature, such as mirages and rainbows, are amazing sights. They arise from the interaction of light with the environment, scenery, or other natural components, producing visually stunning and frequently enthralling phenomena that have the power to fool our senses. Go ahead and continue reading to learn more!.

Optical Illutions

An optical phenomena known as an inferior mirage occurs when the real thing appears to be below the image of a distant object. It happens when a hot surface warms the air layer above it, pushing that layer beneath a denser, colder layer of air.

A rainbow is an optical phenomenon in which a spectrum of light appears in the sky as a result of light being refracted, internally reflected, and dispersed in water droplets. Usually, they take the shape of a circular arc with several colors.

Auroras are naturally occurring light displays that are primarily seen in high-altitude areas surrounding the Artic and Antarctic. They are often referred to as northern lights (aurora borealis) or southern lights (aurora australis). Because of the solar wind-induced disruptions in the magnetosphere, they exhibit dynamic patterns of bright lights.

Horsetail Fall is a seasonal waterfall that runs in the winter and early spring at Yosemite National Park in California. When the weather is perfect in February and the waterfall is flowing, the sunset sun illuminates it, giving it an orange and crimson glow.

A light pillar, sometimes known as an ice pillar, is an atmospheric optical phenomenon in which a vertical beam of light appears above or below a light source. The effect is caused by the reflection of light from small ice crystals hanging in the atmosphere.

In the troposphere, stationary lens-shaped clouds called lenticular clouds occur, usually with their orientation perpendicular to the direction of the wind. When two different-speed air currents collide in the atmosphere, they are created.

In reality, the underwater waterfall isn't a waterfall. This natural optical illusion is created when currents carry silt and coastal sand from Mauritius' southernmost point all the way down to the ocean's bottom.
