The discussion clarifies that a telescope's magnification, specifically a 10X magnification, refers to "angular magnification" rather than "linear magnification." This means that while the tree, which is 15 meters tall, may appear to be viewed from a closer distance, it does not literally increase in height to 150 meters. Instead, the observer perceives the tree as subtending a larger angle, enhancing the visual experience without altering the actual size of the object.
PREREQUISITESAstronomy enthusiasts, optical engineers, educators in physics, and anyone interested in understanding the principles of telescope magnification and visual perception.
The tree is at a large distance from the man. The telescope brings the image of the tree nearer. Can’t we call that feature of the telescope as magnification?Chi Meson said:Is that exactly how the question is stated?
In short, you are correct, but...
Telescope magnification is "angular magnification" not "linear magnification." A 10 X scope does not necessarily mean you will say "oh my god, that looks like a 150 meter tall tree!" You are more likely to have the impression that you are standing closer to the tree such that the subtended angle is increased ten times.
