Understanding Why the Sky is Blue

What is the primary reason the sky appears blue instead of other colors?

• Due to the reflection of the ocean

• Because blue light is absorbed by the ground

• Due to the scattering of blue light by the atmosphere

• Because the sun emits more blue light

What does a prism demonstrate about white light?

• It proves that white light cannot be separated

• It indicates that white light is only made of blue and red

• It reveals that white light is composed of multiple colors

• It shows that white light is a single color

How do light waves differ between red and blue colors?

• Red light has shorter wavelengths than blue light

• Both have the same wavelength

• Blue light has longer wavelengths than red light

• Red light has longer wavelengths than blue light

Why does the sky change color during sunrise and sunset?

• The sky reflects the colors of the ocean

• The atmosphere scatters more red, orange, and yellow light

• The sun emits different colors at these times

• The Earth's rotation changes the color of the sky

What is Rayleigh scattering?

• The bending of light by water droplets

• The scattering of light by gases in the atmosphere

• The absorption of light by the Earth's surface

• The reflection of light by clouds
