<caption><image_31>The image is a screenshot of a question or answer sheet. The question is written in black text on a white background. The text is divided into two sections. 

The first section is titled "Case #1" and it explains that when the light rays will be reflected back into the core medium and undergoes total internal reflection. The second section is labeled "When the angle of incidence is greater than the critical angle, the reflected new again reflects into the same inner reflection."

There is also a diagram on the right side of the image that shows a cross-section of a circle with a point at the center and a line at the outer edge. The line is labeled with the letters "C" and "D" and the line is marked with a dotted line.

At the bottom of the page, there is a space for the student to write their answer.</caption><transcript><audio_32>and this is the total internal reflection when the incident angle is greater than the critical angle the light will be</transcript><caption><image_33>The image is a square with a white background. In the center of the square, there is a blue text that reads "Thank You". The text is written in a simple, sans-serif font and is centered on the square. The overall design is simple and minimalistic.</caption><transcript><audio_34>i hope you understand the concept of total internal reflection</transcript> and this is the total internal reflection when the incident angle is greater than the critical angle the light will be i hope you understand the concept of total internal reflection
