Which of the following statements about total internal reflection is true?
It can occur at any angle of incidence
It requires a denser medium to be on the incident side
It can occur when light travels from air to water
It is a phenomenon exclusive to optical fibers
Total internal reflection requires that the light travels from a denser medium to a rarer medium, making the second statement true.

Q
Q: Which of the following statements about total internal reflection is true?
Solution: Total internal reflection requires that the light travels from a denser medium to a rarer medium, making the second statement true.
Steps: 5
Step 1: Understand what total internal reflection is. It occurs when light hits the boundary between two different media (like water and air) at a certain angle.
Step 2: Identify the types of media involved. A denser medium (like water) has a higher refractive index than a rarer medium (like air).
Step 3: Remember the condition for total internal reflection. It only happens when light travels from the denser medium to the rarer medium.
Step 4: Check the statements given in the question. Look for the one that mentions light traveling from a denser medium to a rarer medium.
Step 5: Conclude that the statement about light traveling from a denser medium to a rarer medium is true, confirming the short solution.
