That depends on the eyepiece, a 9mm eyepiece will have more magnification than a 22mm eyepiece.

It would be 50x. To find the magnification, you just have to multiply the number eyepiece and the number objective. So for example, * A 10x eyepiece and a 40x objective would have a magnification of 400x * A 10x eyepiece and a 100x objective would have a magnification of 1,000x
what should be done if you cannot see anything in high power
An endoscope consists of a tube, a lens, and eyepiece, and a source of light. It is used for performing endoscopies.
It all depends on what one is doing with the telescope. To gaze at the sun, the eyepiece is not used and in astrophotography, the eyepiece may be used but not always.
In Ramsden eyepiece the light comes to focus at the focal point of the objective and then spreads out until it enters the first element . ... In Huygens eyepiece the converging light does not come to focus before entering the first element however,the end result is same the light leave the second element collimated.

it is the cylindrical structure which is used to support the eyepiece. it is the cylindrical structure which is used to support the eyepiece.
It is an instrument used to measure properties of light. It has many uses. find out more here http://en.wikipedia.org/wiki/Spectrometer

You are referring to Ramsden eyepiece. This is a particular lens used in optical microscopes.
A spectrometer measures properties of light of a specific part of the wavelength. It is often used to measure the intensity of a light.
A spectrometer is used to measure different properties of light. Normally one is given a specific wavelength for the light measured when using this instrument.
A Raman spectrometer is a tool that is used for measuring low frequency modes such as vibrations or rotations. It is used mostly in chemistry although it is also used in physics to measure temperature.
