Why is the Sun Yellow and the Sky Blue

The video explains how light scatters in the atmosphere, causing the sky to appear blue. It discusses the scattering of different light frequencies, with blue light scattering more than red. The video also demonstrates how to simulate sky colors on a computer by adjusting blue and red light. It explains why the sun appears yellowish during the day and how sunset colors are richer due to more scattering. The video concludes by describing the dynamic movement of colors in the sky, likening it to a dance.

Which type of light scatters the most in the atmosphere?

• Ultraviolet light

• Green light

• Infrared light

• Red light

What is the primary reason the sky appears blue?

• Blue light is scattered more than other colors

• Blue light is absorbed by the atmosphere

• The atmosphere reflects blue light

• The sun emits only blue light

In a computer simulation, what color is added to a white background to mimic the sky?

• Yellow

• Green

• Deep blue

• Deep red

Why does the sun appear yellowish during the day?

• The sun emits yellow light

• Blue light is scattered away from the line of sight

• The atmosphere absorbs yellow light

• Red light is scattered more than blue

What causes the sky to appear orange and red at sunset?

• The sun emits more red light at sunset

• There is more air for light to scatter off before reaching the observer

• The atmosphere absorbs blue light

• The sun is closer to the Earth at sunset
