Question 1.
What is total internal reflection?
Show hintHide hint
Think about what happens when light goes from one medium to another.
Question 2.
Define critical angle.
Show hintHide hint
It's related to the transition from denser to rarer mediums.
3Question 3.
What angle is critical for total internal reflection to occur?
- 30 degrees
- 48.75 degrees
- 90 degrees
Show hintHide hint
Refer to the table of critical angles.
4Question 4.
True or False: All angles greater than the critical angle will result in refraction.
- True
- False
Show hintHide hint
Think about the behavior of light in different mediums.
Question 5.
You are given a material with a refractive index of 1.6. Calculate the critical angle for light transitioning from this material to air.
Show hintHide hint
Use the inverse sine function on your calculator.
Question 6.
Discuss the implications of bending light in optical fibers when they are bent as well as strained.
Show hintHide hint
Consider how changing the angle of incidence can impact total internal reflection.
