When we stand quietly watching the sunset, the endless hues of the setting sun become mesmerizingly beautiful. The sun, having shed the glare of the day and the heat of noon, takes on a gentle and serene glow in the evening's quiet.

The setting sun bathes everything in a soft, golden-red light. Throughout history, sunsets have been imbued with various beautiful meanings, often becoming symbols of peace, beauty, and the passage of time.

But have you ever wondered why the sunset appears red when you see that glowing horizon?

On a clear day, the sky tends to appear blue. This is because blue light, which has a short wavelength, scatters more easily than other colours. This scattering causes the sky to appear azure during the day. However, at sunset, the phenomenon changes dramatically due to the dispersal of light.

As the sun sets and its light passes through the atmosphere at a more horizontal angle, it travels through a much thicker layer of the atmosphere compared to when it is overhead. During this time, the shorter wavelengths of light, such as blue and violet, are scattered out of the line of sight. The longer wavelengths, like red and orange, become more prominent and are what we predominantly see, giving the sunset its characteristic red hue.

Humidity in the air also significantly influences the colour of the setting sun. High humidity means there are many large water droplets suspended in the air, which scatter light differently depending on their size. For instance, smaller droplets tend to scatter blue light, while larger droplets, with a radius of 0.5 to 1 micron, scatter mostly red light. Consequently, the sky near the horizon can sometimes display a range of colours, from purple to brownish-red. The greater the water vapour content in the atmosphere, the more vibrant and colourful the sunset becomes.

Now, let’s explore some of the most beautiful sunsets around the world:
