Understanding Rainbows

The video explains that rainbows are circular, not arches, and are formed by light refracting and reflecting in water droplets. It details the conditions needed for a rainbow, the process of refraction, and how light splits into different colors. The video also discusses the best times to view rainbows and how to create them using a sprinkler or spray bottle.

What shape is a rainbow actually?

• A straight line

• A triangle

• An arch

• A circle

Why do rainbows appear as arches to us?

• Because we only see the part above the horizon

• Because of the sun's position

• Because they are actually arches

• Because they are incomplete circles

What is a rainbow primarily composed of?

• Water droplets

• Gold

What happens to sunlight when it enters a water droplet?

• It bends and changes direction

• It turns into water

• It stops

• It speeds up

Which process separates sunlight into different colors?

• Refraction

• Diffusion

• Reflection

• Absorption

Which color in a rainbow has the longest wavelength?

• Violet

• Red

• Green

• Blue

Which color appears on the outside of a rainbow?

• Violet

• Red

• Indigo

• Green

What determines the order of colors in a rainbow?

• The speed of light

• The size of the water droplets

• The wavelength of the colors

• The angle of the sun

When is the best time to observe a rainbow?

• At noon

• In the early morning or late afternoon

• At midnight

• In the evening

What can you use to create a rainbow at home?

• A glass of water
