Length of Astronomical Telescope when Image Forms at Infinity Solution

STEP 0: Pre-Calculation Summary
Formula Used
Length of Telescope = Focal Length of Objective+Focal Length of Eyepiece
Ltelescope = fo+fe
This formula uses 3 Variables
Variables Used
Length of Telescope - (Measured in Meter) - The length of Telescope is the distance between the objective lens and the eyepiece.
Focal Length of Objective - (Measured in Meter) - The Focal Length of Objective is the focal length of the lens in front known as the objective lens uses to focus an image.
Focal Length of Eyepiece - (Measured in Meter) - The Focal Length of Eyepiece is the distance from the principal plane of the eyepiece where parallel rays of light converge to a single point.
STEP 1: Convert Input(s) to Base Unit
Focal Length of Objective: 100 Centimeter --> 1 Meter (Check conversion here)
Focal Length of Eyepiece: 4 Centimeter --> 0.04 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Ltelescope = fo+fe --> 1+0.04
Evaluating ... ...
Ltelescope = 1.04
STEP 3: Convert Result to Output's Unit
1.04 Meter -->104 Centimeter (Check conversion here)
FINAL ANSWER
104 Centimeter <-- Length of Telescope
(Calculation completed in 00.020 seconds)

Ltelescope = fo+fe

Explain working of an astronomical telescope.

The rays coming from a distant object fall on the objective as a parallel beam at some angle say "a" and these rays after refraction and passing through the objective converge at its focus and make an inverted & real image AB. This image acts as an object for the eyepiece. The distance of the eyepiece is so adjusted that the image AB lies within the focal length of the eyepiece. The eyepiece forms the final image. The final image is magnified, virtual, and inverted with respect to the object. The final image is formed at infinity.

What are the uses of an astronomical telescope ?

Astronomical Telescope, a device used to form magnified images of distant objects. The telescope is undoubtedly the most important investigative tool in astronomy. It provides a means of collecting and analyzing radiation from celestial objects, even those in the far reaches of the universe.
