Auroras are a sign that the sun and earth are connected by more than sunlight, they indicate that something is happening in space. The aurora forms when charged particles emitted from the sun during a solar flare penetrate the earths magnetic shield and collides with the atoms and molecules in our atmosphere.
The speed of light in the medium of refractive index 1.1 is 272,538,598 m/s.
<h3>What is speed?</h3>
Speed is given as the distance traveled by the object in unit of time. Light is the collection of photons, and it travels in different mediums at different speeds.
The speed of light in the medium of refractive index 1.1 is given as:
![\rm Speed\;of\;light=\dfrac{speed\;in\;air}{refractive\;index}](https://tex.z-dn.net/?f=%5Crm%20Speed%5C%3Bof%5C%3Blight%3D%5Cdfrac%7Bspeed%5C%3Bin%5C%3Bair%7D%7Brefractive%5C%3Bindex%7D)
The speed of light in air is 299,792,458 m/s. Substituting the values:
![\rm Speed\;of\;light=\dfrac{299,792,458\;m/s}{1.1}\\\\Speed\;of\;light= 272,538,598\; m/s](https://tex.z-dn.net/?f=%5Crm%20Speed%5C%3Bof%5C%3Blight%3D%5Cdfrac%7B299%2C792%2C458%5C%3Bm%2Fs%7D%7B1.1%7D%5C%5C%5C%5CSpeed%5C%3Bof%5C%3Blight%3D%20272%2C538%2C598%5C%3B%20m%2Fs)
Thus, the speed of light in the medium of refractive index 1.1 is 272,538,598 m/s.
