A sunrise and sunset happen when the Sun appears to change color because light travels through more air as it goes lower in the sky.
Imagine the Sun is like a big, bright flashlight. During the day, its light travels straight through the air and reaches us quickly. But when the Sun is near the horizon, at sunrise or sunset, its light has to travel through more air before it gets to our eyes. This extra journey makes the sky look different colors.
Why the Sky Changes Color
The sky changes color because of tiny particles in the air, like dust and water droplets. These act like little filters that catch some colors of light and let others pass through.
- When the Sun is high up, the sky looks blue because the shorter blue wavelengths travel straight to us.
- But when the Sun is low, its light travels through more air, and those tiny particles catch the blue and green light. What’s left is red, orange, and pink, making the sky look like it's on fire!
It’s like dipping a flashlight in water and seeing how the colors change as you move it closer or farther away. Magic, right? A sunrise and sunset happen when the Sun appears to change color because light travels through more air as it goes lower in the sky.
