¿Qué es un arco iris?

The video explains how rainbows form, requiring sunlight at a low angle and water droplets. Light slows and refracts in water, separating into colors due to different wavelengths. This separation creates the rainbow arc, visible at specific angles. The illusion of a rainbow persists as new droplets recreate it, making it impossible to reach.

What are the two conditions necessary to see a rainbow?

• The sun must be setting and the air must be dry.

• The sun must be directly overhead and there must be no clouds.

• The sun must be at a low altitude and light must reflect off water.

• The sun must be at a high altitude and the sky must be clear.

What happens to light when it passes from air to water?

• It remains at the same speed and direction.

• It speeds up and changes color.

• It slows down and changes direction.

• It speeds up and continues in a straight line.

Why do different colors separate when light passes through a raindrop?

• Because each color has the same wavelength.

• Because each color has a different wavelength.

• Because all colors travel at the same speed.

• Because the raindrop absorbs some colors.

At what angles do the colors of a rainbow typically appear?

• Between 30 and 32 degrees.

• Between 40 and 42 degrees.

• Between 60 and 62 degrees.

• Between 50 and 52 degrees.

Why is it impossible to reach the end of a rainbow?

• Because rainbows are only visible from a distance.

• Because new water droplets create the illusion as you move.

• Because the colors fade as you get closer.

• Because rainbows are only visible during certain times of the day.
