Your ray tracing is all right. The ray entering parallel with the axis goes through the focus on the other side of the lens.toothpaste666 said:
Ray tracing for convex lens is a technique used to determine the path of light rays as they pass through a convex lens. This technique helps in understanding how images are formed and how the lens behaves in different situations.
Ray tracing for convex lens involves drawing a ray diagram with three principal rays to determine the path of light rays through the lens. These rays include the parallel, focal, and center rays. By tracing these rays, we can determine the location and size of the image formed by the lens.
The images formed by convex lens have three main properties: they are real, inverted, and diminished. This means that the image is formed on the opposite side of the lens, it is upside down, and it is smaller in size compared to the object.
The focal length of a convex lens determines the size and location of the image formed. A shorter focal length will result in a larger and closer image, while a longer focal length will result in a smaller and farther image.
Ray tracing for convex lens has many practical applications, such as in designing and understanding optical instruments like microscopes, telescopes, and cameras. It is also used in the field of optics to analyze and improve the performance of lenses and other optical systems.
