SUMMARY
The length of a refracting telescope is determined by the focal length of its primary lens. In this case, with a lens diameter of 1.02 m and a focal length of 19.4 m, the telescope must be approximately 19.4 m long to achieve an image magnification of 40 times. This calculation is based on the fundamental principles of optics, specifically the relationship between focal length and magnification.
