The type of image produced by the objective lens in a refracting telescope.

Explanation of Solution
Introduction:
Refracting telescope is an optical telescope in which lens is used as its objective to form an image of an object under observation. Objective lens bends the light rays that are parallel to the optic axis of the lens and focuses them in to a focal point.
Refracting telescope is composed of two lenses. Objective lens is the first lens. This forms the real and inverted image inside the focal length of eyepiece, which is the second lens. The real image produced by an objective lens acts as an object for the second lens (eyepiece). Eyepiece produces a virtual and magnified image that can be seen by an observer.

- A Geiger-Mueller tube is a radiation detector that consists of a closed, hollow, metal cylinder (the cathode) of inner radius ra and a coaxial cylindrical wire (the anode) of radius г (see figure below) with a gas filling the space between the electrodes. Assume that the internal diameter of a Geiger-Mueller tube is 3.00 cm and that the wire along the axis has a diameter of 0.190 mm. The dielectric strength of the gas between the central wire and the cylinder is 1.15 × 106 V/m. Use the equation 2πrlE = 9in to calculate the maximum potential difference that can be applied between the wire and the cylinder before breakdown occurs in the gas.
