Answer
The answer is B, incidence. This is because angle Y is formed between the incoming ray of light and the normal line at the point of incidence on the glass block.

Answer
To test the conclusion that angle Y is directly proportional to angle X, the student should conduct multiple trials while measuring angle Y for various known values of angle X. After gathering sufficient data, the student can plot a graph of angle Y against angle X. If the relationship is linear and passes through the origin, it would confirm that angle Y is directly proportional to angle X.
Step 3
Calculate the frequency of yellow light.
