AI Thread Summary
The problem involves calculating the magnification of a telescope with a focal length of 200 cm for the objective and 1 cm for the eyepiece. The user initially calculated the magnification using the formula M = Fo/Fe, resulting in 200, but the expected answer is 20. The confusion arises from the fact that when viewing an object at infinity, the correct formula for magnification is M = Fo/Fe, but it must also account for the distance at which the eyepiece focuses light. The key takeaway is that the magnification is influenced by the effective focal lengths and the viewing distance, leading to the correct answer of 20. Understanding the relationship between focal lengths and object distance is crucial for accurate calculations in optics.

I have been working on this problem for HOURS! PLease helpe me!

Homework Statement


The objective of a telescope has a focal length of 200 cm and its eye piece has a focal length of 1 cm. What is the magnification of this telescope when viewing an object at infinity??


Homework Equations





The Attempt at a Solution



I thought ...
M = Fo/Fe which would = 200 but the answer is 20! Why? Does infinity have something to do with it??

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

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...
