Why Do You See Colorful Rainbow Patches On A Wet Road?
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...

GCSE Physics - Refraction of waves #63
In this video we cover the following: - What 'refraction' means - When refraction occurs - How to draw ray diagrams for the refraction of light - The idea that during refraction, the wavelength of a wave stays constant, and it is the...

Mirage: Why Does It Look Like There's Water On The Road?
The fake puddles of water that we see on the road on a sunny day is due to an optical phenomenon called a mirage, which is caused by the refraction (or bending) of light rays due to different temperatures of the air above the road. On a...
