Light Behavior and Optical Phenomena

What happens to the sun's visibility due to atmospheric refraction?

• The sun is visible for a few minutes after it sets.

• The sun changes color.

• The sun appears larger in the sky.

• The sun disappears immediately after setting.

What causes a mirage to appear like water on the ground?

• The reflection of the sky on the ground.

• The movement of clouds.

• The bending of light rays in hot air.

• The presence of actual water on the ground.

Why do mirages shimmer like water?

• Because of the presence of actual water.

• Because of the mixing of hot and cold air.

• Because of the movement of the ground.

• Because of the reflection of sunlight.

How does light behave when it enters a water droplet to form a rainbow?

• It speeds up and travels straight.

• It reflects off the surface and exits immediately.

• It changes color instantly.

• It slows down and bends towards the normal.

Why do rainbows display different colors?

• Because each color travels at the same speed.

• Because each color is refracted at a different angle.

• Because each color is reflected multiple times.

• Because each color is absorbed by the air.
