Length Telescope Telescopes

AI Thread Summary

To achieve an image 40 times bigger in a refracting telescope with a lens diameter of 1.02 m and a focal length of 19.4 m, the telescope's length must be calculated based on the magnification formula, which relates the focal lengths of the objective and eyepiece lenses. The required length of the telescope will be determined by the focal length of the eyepiece lens needed to achieve this magnification. Additionally, understanding the relationship between the focal lengths and the telescope's overall design is crucial for optimal performance. For further insights into elementary optics, resources that explain these principles in detail can be beneficial. The calculations and principles discussed are essential for anyone interested in telescope design and functionality.

in a refracting telescope, the lens's diameter is 1.02 m and its focal length is 19.4 m.
how long must the telescope be to get an image, 40 times bigger?

i would also like to get a link to a site explaining this kind of elementary optics.

just saw the warning, please don't delete my posts :S they are in a close enough format i think..

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'How to find eddy current (circular) path in this pendulum experiment?'

Does the direction my second finger points in indicate the literal direction of magnetic field at that point in space, or do I need to further use right hand rule or something for a circular path around the finger
