A) On a hot day, the temperature on the Fahrenheit scale changes by 10 oF. Calculate the corresponding change on the Kelvin scale. B) Four liquids in a research laboratory have refractive indices of 1.54, 1.23, 1.37 and 1.42 respectively. In which of these liquids will you expect light to travel the fastest and the slowest? Calculate the ratio of the fastest speed to the slowest speed. Explain your reasoning
