Spring is coming, the road to spring.
For the last week, the sky over the city has been blue and the sun is shining. This is a wonderful weather that brings me a lot of joy. After a long and cloudy winter, I enjoy the sunny weather. The blue sky attracts me.
As a photographer, I understand that light is one of the most important phenomena in the world.
Without light, life is not sweet.
In short, good weather is a thrill.
And on such a day, it is best to leave the city and go to the Russian forest.
There is still no foliage on the trees and green can only be found on conifers.
White birch trees against a blue sky also look very cool. It can be seen that nature is just beginning to wake up from hibernation.
Of course, the coolest thing about all this splendor is the blue sky. By the way, why is the sky blue. This question was recently asked by my daughter. And I thought.
It is clear that color is our human perception of a certain physical quantity. The sun's rays enter the atmosphere and photons of light collide with air molecules. Light scattering occurs and blue is the first victim of this scattering. The fact is that blue corresponds to the shortest wavelength of the visible spectrum.
This scattering determines the color of the sky.
Longer wavelength light beams are also scattered, but much less. They fly to the ground.
From the point of view of physics, this is all very interesting, but not romantic. But to come to the forest and walk, breathe fresh air and feel the sun's rays on your skin - it's very romantic.
