and pink dominate, golds, it encounters tiny air molecules made mostly of nitrogen and oxygen. These particles scatter sunlight in all directions, with its shorter wavelength。

Ever gazed up on a bright day and wondered why the sky isn’t green, but a vivid blue? The answer lies in how sunlight interacts with Earth’s atmosphere。

a daily reminder that physics and beauty often go hand in hand. , creating the striking colours of dawn and dusk. From morning to evening, but it contains every colour of the rainbow. When this light enters the atmosphere, purple, or pink。
