Rayleigh scattering is an optical phenomenon where we see a haze surrounding a distant object, the cause of which is the light rays impinging on the scattered small particles in the atmosphere. These particles are in the form of oil, water droplets, air molecules, and dust. As the sunlight hits these particles, the light rays reflect crea, ting an optical illusion, allowing our eyes to see the bluish hue.

As in the Blue Mountains, where it is covered by gums and eucalyptus forests, organically oil-emitting vegetation, the scattering phenomenon becomes more effective. Thus, the azure colour, a sapphire, transparent blue haze appearance covering the hills of Carmarthen and Lansdowne, the old names of the mountains. It was Arthur Phillip who named the hills in 1788. But today, the term “Blue Mountains” remained due to its mystical hue. And it will be its name in the years to come as in the past.
