Your answer for air is correct. Glass has a higher refractive index compared to water.
So the answers should go in this order: Water, Glass, Air
Explanation:
Light moves slower in glass, so glass has a higher refractive index than water. This means that light is refracted at a greater angle
Place 25 equally sized pieces of paper in a hat. Of the 25, 5 read “defective” and the rest read “working”.
(<u>100 m / 10.4 sec</u>) x (3600 sec/hr) x (mile/1609.344m) = <em>21.5</em> miles per hour
Rounded to the nearest whole number, that's<em> 22 mph</em> .
