Only those with high IQ can answer where the arrow is pointing in 10 seconds

Optical illusions are visual phenomena where our brain perceives images differently from reality.

They occur due to how our eyes and brain process visual information, sometimes leading to misleading or distorted perceptions.

One such interesting illusion shared by optics4kids.org shows a picture of a glass half-filled with water.

In the image, there is a paper behind the glass that shows two arrows.

The readers are challenged to find the direction in which the arrows point—and they have to do it in 10 seconds.

So do you want to give it a try?

The image may look confusing at times as it suggests both the arrows are pointing in a different direction.

However, if you observe carefully, as the water is poured into the glass, it shows that both of them are marked in the same direction. This phenomenon is called refraction illusion.

A Refraction Illusion occurs when light bends as it passes through different mediums, such as water, glass, or air layers of varying densities. This bending of light, known as refraction, can create distorted, displaced, or magnified images, tricking our perception.

Refraction illusions highlight how light behaves and how our brains interpret the bending of light, sometimes leading to false perceptions.
