I WONDER - Why Are Peacock Feathers So Colourful?

The video discusses how microscopic crystal-like structures on peacock feathers refract light differently based on their movement. This phenomenon is also observed in hummingbirds and butterflies, where similar structures on their wings create unique light effects.

What is the primary feature of Peacock feathers discussed in the video?

• They have microscopic crystal-like structures.

• They are colorful due to pigments.

• They are waterproof.

• They are used for flight.

How do the crystal-like structures on Peacock feathers affect light?

• They emit light.

• They refract light differently based on movement.

• They reflect light uniformly.

• They absorb light completely.

What is the role of movement in the light refraction of Peacock feathers?

• It has no effect.

• It changes the color of the feathers.

• It alters how light is refracted.

• It makes the feathers invisible.

Which other creatures exhibit similar light refraction effects as Peacock feathers?

• Hummingbirds and some butterflies.

• Eagles and sparrows.

• Dolphins and whales.

• Lions and tigers.

What is a common feature between Peacock feathers and butterfly wings?

• Both are used for camouflage.

• Both have similar crystal-like structures affecting light.

• Both are primarily used for flight.

• Both are made of the same material.
