The smallness of the critical angle Θc for diamond means that light is easily "trapped" within a diamond and eventually emerges from the many cut faces. This makes a diamond more brilliant than stones with smaller n and larger Θc. Traveling inside a diamond, a light ray is incident on the interface between diamond and air.

What does critical reflection mean?
Critical reflection is the process of analyzing, questioning, and evaluating our own beliefs, assumptions, and actions. It involves challenging our perspectives and seeking deeper understanding to enhance learning and personal growth. Through critical reflection, we can gain insight into the underlying meanings and implications of our thoughts and behaviors.
Will you get a more total internal reflection with a medium that has a small critical angle or with OR that has a large critical angle?
You will get more total internal reflection with a medium that has a smaller critical angle. A smaller critical angle means that light is more likely to be reflected back into the medium rather than refracted out of it.
What is the different between a reflection on mirror and water?
Reflection from water will occur only beyond the critical angle between air and water. Reflection from a mirror will occur at all angles.
What will happen if the angle of incidence is bigger than the critical angle?
A complete reflection will occur
Why is personal reflection is critical to effective group work practice?
they consist of set of started assumptions
What happens to the light ray when the angle of incidence is greater than the angle of total reflection?
it is not the angle of total reflection, it is the critical angle. and when the angle of incidence is greater than the critical angle, total internal reflection takes place and as it is necessary for total internal reflection to take place that the ray must travel from denser to rarer medium so, when it occurs, the ray is reflected bach into the denser medium.
Why do you believe what you believe?
I believe what I believe because of a combination of personal experiences, evidence, critical thinking, and reflection.
What are the kinds of reflections?
the two ways in which a surface can reflect light are regular reflection and diffuse reflection.
How does total internal reflection depend on the angle of incidence of light rays?
Total internal reflection occurs when the angle of incidence is greater than the critical angle. The critical angle is the angle at which the refracted ray would be at 90 degrees to the normal. If the angle of incidence is less than the critical angle, the light ray will be refracted out of the material.
What tajes place when the angle of incidence is smaller than the critical angle?
Refraction and partial internal reflection occurs
Is fiber optic cable related to refraction?
Not really. More to do with reflection and the critical angle which gets it to reflect for infinity .
Why is a small critical angle desirable for optical fibers What problems could be caused if the critical we're increased?
because a smaller critical angle means that it is easier for total internal reflection to occur, which is the desirable quality in an optical fibre.
