A ray of light is refracted as it passes into a glass prism. The speed of light in air is 2.98 * 10^5 km/sec and the speed of light in glass is 1.98 * 10^5 km/sec, what is the index of the refraction of the glass?

I got 1.5.....not sure how to label it or if it's even right.

Easy you divide speed in air by speed in the glass

2.98*10^5/1.98*10^5 =1.5
