Why is the Sky Blue?

The Sky always appear in Blue color even though we have a variety of other colors- do you know why?

It's because Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. 

This is why we see blue sky most of the time.

What is a Harvest Moon ?

The Harvest Moon is the full Moon nearest the start of fall or the autumnal equinox. This usually means it coincides with the September full Moon, though it can also fall nearer to the October full Moon, occurring anywhere from two weeks before to two weeks after the equinox. In  2017 , the Harvest Moon will rise on  October 5  at 2:40  P.M. EDT. WHY IS IT CALLED THE HARVEST MOON? For several evenings, the moon rise comes soon after sunset. This results in an   abundance of bright moonlight early in the evening , which was a traditional aide to farmers and crews harvesting their summer-grown crops. Hence, it’s called the “Harvest” Moon!

What is HUNTERS MOON ?

The term “ Hunters Moon ” is used traditionally to refer to a full moon that appears during the month of October. It is preceded by the appearance of a “Harvest Moon”, which is the full moon closest to the autumnal equinox (which falls on the 22nd or 23rd of September). It is also known as a sanguine or “ Blood Moon ". The Hunter’s Moon typically appears in October, except once every four years when it doesn’t appear until November.  The name dates back to the First Nations of North America. It is so-called because it was during the month of October, when the deers had fatted themselves over the course of the summer, that hunters tracked and killed prey by autumn moonlight, stockpiling food for the coming winter.

What is Reflection of Light ?

Reflection is a very common word and is related to the fields of physics and mathematics. The basic meaning of a reflection is  ‘Something Returned in Response’ . Even in our conversation we use this term at times, to mean a some one’s reaction. In optics, it relates to an image of an object. Light rays are basically wave motions and they are capable of being reflected by an interface in between two mediums. Such interfaces are called  Light Reflectors .  The most common Light reflector is the one we use many times a day, which is nothing but a plane mirror. But it is not only a plane mirror reflects light. Even a curved mirror does that though the nature of reflection of light by curved mirrors is different.
