# What Year Is Light

**That is a 6 with 12 zeros behind it.**

**What year is light**.
On the scale of the universe measuring distances in miles or kilometers doesnt cut it.
More p recisely one light-year is equal to 9500000000000 kilometers.
To obtain an idea of the size of a light-year take the circumference of the earth 24900 miles lay it out in a straight line multiply the length of the line by 75 the corresponding distance is one light-second then place 316 million similar.

This seems really fast but objects in. Light travels at a speed of 186000 miles or 300000 km per second. Want to find out more about Tigtag.

In most everyday circumstances the properties of light can be derived from the theory of classical electromagnetism in which light is described as coupled electric and magnetic fields propagating through space as a traveling wave. The new National Curriculum introduced in 2014 requires children in Year 3 to understand that they need light to see and that light is reflected from surfaces. So in one year it can travel about 10 trillion km.

The light-year is a measure of distance not time. What is a light year. However this wave theory developed in the mid-19th century is not sufficient to explain the properties of light at very low intensities.

At that level a. In Year 3 children begin to fully explore light. Light is produced through a phenomenon known as electromagnetic radiation which is composed of both a magnetic and an electrical component.
