Understanding Refraction in Animals

How does refraction aid in the vision of vertebrates?

• By absorbing light into the retina

• By amplifying sound waves

• By slowing down and refracting light to focus images

• By reflecting light away from the eyes

What is the primary cause of structural coloration in certain animals?

• Microscopic surface structures

• Temperature changes

• Chemical reactions

• Pigments in the skin

Which of the following is NOT a result of structural coloration?

• Colors in butterfly wings

• Feather colors in some birds

• Colors in certain insects

• Pigment-based colors in flowers

What happens when the peaks of refracted waves align with the valleys of another?

• The color vanishes

• The color is intensified

• The light is absorbed

• The light is scattered

What factor influences the shimmering iridescent colors seen in some animals?

• The animal's diet

• The angle of light and viewer movement

• The temperature of the environment

• The animal's speed
