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

The video explains the phenomena of light reflection and refraction, focusing on how these principles create colorful patterns on roads during rainy days. It describes how light interacts with oil and water, leading to interference that produces a spectrum of colors. The video highlights the everyday application of these optical principles, emphasizing the science behind the mesmerizing patterns.

What happens when light hits a surface and bounces back?

• Refraction

• Reflection

• Diffusion

• Absorption

Why do we see rainbow patterns on roads only on rainy days?

• The oil on the road evaporates on sunny days.

• The sunlight is too strong on sunny days.

• The oil mixes with water to create colors.

• The oil and water layers create varying thicknesses.

What are the three media involved in the formation of rainbow patterns on roads?

• Air, oil, and glass

• Oil, water, and glass

• Air, water, and sand

• Air, oil, and water

What is the result when light rays reinforce each other?

• Polarization

• Diffraction

• Constructive interference

• Destructive interference

What causes the difference in the path length of light rays in an oil film?

• The color of the oil

• The speed of the light

• The thickness of the oil film

• The temperature of the road
