The image depicts a right-angled triangular prism with a light ray incident on it. Here's a detailed description: 1. **Ray Diagram**: - An incoming light ray approaches the flat surface of the prism horizontally from the left side. - Upon reaching the surface, the light ray enters the prism and bends according to the angle of refraction. 2. **Prism Details**: - The prism is oriented such that the right angle is at the bottom left corner of the triangle. - The hypotenuse of the triangle makes an angle labeled as \( \theta \) with the base. 3. **Dashed Line**: - Inside the prism, a dashed line represents the path of the refracted ray through the prism. This diagram illustrates the basic principles of refraction in optics, where the light ray changes direction due to a change in medium, highlighting the concept of the angle of incidence and refraction within a prism.

The index of refraction for material 1 is 1.36; for material 2 it is 1.66. Light travels 1.5 m in the first material before hitting the second material, where it travels another 1.5 m. What is the total time taken for the light to travel the total distance? Speed of light c = 2.998 x 108 m/s Total time in the two materials = = 1.51 S Reflect on the order of magntitude of this time. Is this a perceptible time delay? ! No, that's not the correct answer.
