The diagram shows the results of copying waves in both analog and digital forms. What conclusion about the reliability of analog
and digital waves is supported by the data?

Answer:
Explanation:
Total internal reflection can happen when light goes from a medium with higher refractive index (in this case, glass) to a medium with lower refractive index (in this case, water).
Snell's Law tells us that , where the <em>i</em> stands for incident (in this case, glass) and the <em>r</em> for refracted (in this case, water). We want to know when
, that is, when
, and this happens when the incident angle is:
Which for our values means:
