Light pillars are optical phenomena that occur in extremely cold atmospheres, when flat ice crystals form close to the ground. They reflect natural and artificial light in columns that extend through the sky. This captivating spectacle...

A projector is a machine that projects an image onto a screen. LCD projectors work by shining a light through three LCD screens. When the colored light passes through these three screens, they relay three versions of the same scene....

The appearance of patches of different colors on roads on a rainy day is due to a combination of oil, water, and light rays. When it rains, the oil on the road comes in contact with water, and the light rays bounce off the surface of the...

If you are still living under the assumption that the moon can only be seen in the night sky, you’re incorrect! The fact is that the moon is always hanging around our planet; sometimes, it’s visible during the day (given you have the...
