What are the differences between teleconverters and extension tubes in terms of their impact on image quality and magnification capabilities?

Teleconverters and extension tubes are both accessories used in Photography to change the magnification capabilities of a lens. Teleconverters increase the focal length of a lens, resulting in higher magnification, but they can also reduce image quality due to additional glass elements. Extension tubes, on the other hand, increase the distance between the lens and the camera sensor, allowing for closer focusing and higher magnification without affecting image quality.
