Sir James Jeans was a British physicist and astronomer known for his popular science books. His talent lay in translating difficult scientific subjects into easily understandable language for popular readers. The sky appears blue because shorter wavelengths like violet and blue light scatter more readily than red wavelengths from air molecules and particles – this…
As early as 1500, Leonardo da Vinci attempted to understand why the sky was blue. He kept a notebook that documented sunlight passing through wood smoke, and appears to have grasped light scattering phenomena. The sky appears blue because shorter blue wavelengths are scattered more effectively by atmospheric particles than longer red wavelengths. Sunlight As…
As sunlight enters Earth’s atmosphere, its light is dispersed through gases and particles in the atmosphere by various gases and particles; light toward the blue end of the spectrum is scattered more widely than red end light, giving Earth its signature blue hue. As writers, it is our responsibility to pay close attention to reader…
Blue skies are beautiful, soothing, and inspiring – offering us our daily dose of motivation. Have you ever found yourself asking why the sky is blue? Many curious individuals do, and while there may be several reasons for its color, one in particular stands out: atmospheric conditions. The Sun A clear blue sky symbolizes hope,…
As sunlight passes through Earth’s atmosphere, it becomes blue due to scattering caused by Rayleigh Scattering as well as other effects. Light rays are dispersed into all directions by oxygen and nitrogen molecules in the atmosphere, with blue wavelengths dispersing more widely than red ones – giving sky its distinctive hue. Rayleigh Scattering As light…
The Sky Tower stands as an icon on the city skyline and can be seen for miles around. Built of steel, its 105-meter height ensures it can withstand earthquakes with high magnitude as well as strong winds. The tower lights up in various colors to symbolize respect and solidarity for charities, community initiatives, holidays and…
Blue is a relaxing color that inspires trust and calmness, representing water and the sky. Let these hilarious blue jokes add some humor and relaxation into your day! The sky appears blue due to sunlight being scattered by gases and particles in the atmosphere, allowing only shorter wavelengths from reaching our eyes and creating what…
Children are naturally curious about their world. A question often raised is: Why is the sky blue? Light is scattered as it travels through the atmosphere by air molecules; blue wavelengths tend to be more strongly scattered. The Sun’s Light The Sun emits light over an array of wavelengths (or colors). Our eyes, however, perceive…
At night, the sky is dark blue due to atmospheric scattering of sunlight. Blue light scatters more readily than red light due to shorter wavelengths being more easily diffused into space. Answer is straightforward physics: as the Sun gets lower in the sky, more of its light passes through your atmosphere to reach you –…
