Collision detection in ray tracing works by casting rays from the camera through each pixel on the screen and checking if they intersect with any objects in the scene. If a ray intersects with an object, the algorithm calculates the point of intersection and determines the color of that pixel based on the object's material properties and lighting conditions. This process is repeated for each pixel in the image to generate a realistic rendering of the scene with accurate shadows, reflections, and refractions. **
