How Do Rainbows Form?

The video explains how light waves behave, focusing on the formation of rainbows. Sunlight, composed of various wavelengths, enters raindrops, refracts, and reflects to form a spectrum of colors. The video details how light travels in waves, the role of wavelength in color perception, and the conditions necessary to view a rainbow. It also explains why rainbows form an arc due to the angle of incoming sunlight.

What happens to sunlight when it enters a raindrop?

• It splits into multiple colors.

• It turns into a single color.

• It disappears.

• It becomes brighter.

Which of the following determines the perceived color of light?

• The source of light

• The speed of light

• The wavelength of light

• The intensity of light

What is the sequence of colors in the visible spectrum?

• Violet, indigo, blue, green, yellow, orange, red

• Green, yellow, red, blue, indigo, violet, orange

• Red, orange, yellow, green, blue, indigo, violet

• Red, blue, green, yellow, orange, violet, indigo

Where should the sun be positioned for a rainbow to be visible?

• Directly overhead

• Behind you

• In front of you

• To your left

Why do rainbows form an arc shape?

• Because of the circular cone angle formed by sunlight rays

• Due to the curvature of the Earth

• Because raindrops are spherical

• Due to the wind direction
