Which of these diagrams most accurately illustrates what happens when a ray of light from underwater strikes the smooth surface of the water at an angle of incidence greater than the critical angle?

Explanation :

When the ray of light from underwater strikes the smooth surface of the water at an angle of incidence greater than the critical angle, then total internal reflection occurs (TIR). The ray of light must pass from the denser medium to rarer medium.

When the angle of incidence is equal to 90, the angle formed is called critical angle.

In this case, the diagram (D) shows the angle of incidence greater than the critical angle and hence TIR occurs.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
