A student places two lenses as pictured above in the hope of creating a telescope.
What is the magnifying power of this telescope?

When answering the questions below indicate with a "V" for virtual, "R" for real, "M" for magnified, "E" for reduced, "U" upright and "I" for inverted.

The image fromed by the first(weak) lens is __R__, __I___, __E___

The image fromed by the second(strong) lens is _V___, __U___, __M___

A student constructed the telescope shown above.

Will this arrangement of lenses work as a telescope? No! The image formed by the lens nearest to the eye is too far away, behind the eye, to be seen .

When answering the questions below indicate with a "V" for virtual, "R" for real, "M" for magnified, "E" for reduced, "U" upright and "I" for inverted.

The image fromed by lens 1 is _R___, __U__, __M___

The image fromed by lens 2 is _R___, __I___, ___E__

The image formed by the second lens is real, inverted and reduced when compared to the distant object. The image formed by the first lens falls between one and two focal lengths of the second lens. The image produced by the second lens is between 10 and 20 cms from the lens, real, magnified and inverted (when compared with the first image).
