A Cassegrain telescope is a reflecting telescope that uses two mirrors, the secondary mirror focusing the image through a hole in the primary mirror (similar to that shown in the figure (Figure 1)). You wish to focus the image of a distant galaxy onto the detector shown in the figure. If the primary mirror has a focal length of 2.5 m, the secondary mirror has a focal length of -1.5 m and the distance from the vertex of the primary mirror to the detector is 15 cm. Figure 1 of 1 Part A What should be the distance between the vertices of the two mirrors? Express your answer using two significant figures. VO 阿 ΑΣΦ 1 ?
