Correct Answer: 2.5
Solution and Explanation
The Ripple Symmetry Index (RSI) is defined as the ratio of the stoss side length to the lee side length of a ripple. In the given figure, the stoss side length is 10 cm and the lee side length is 4 cm.
RSI is calculated as follows:
RSI = stoss side length / lee side length
Plugging in the given values, we have:
RSI = 10 / 4 = 2.5
The calculated RSI value is 2.5
