Length of Astronomical Telescope Solution

STEP 0: Pre-Calculation Summary

Formula Used

Length of Telescope = Focal Length of Objective+(Least Distance of Distinct Vision*Focal Length of Eyepiece)/(Least Distance of Distinct Vision+Focal Length of Eyepiece)
L_telescope = f_o+(D*f_e)/(D+f_e)
This formula uses 4 Variables

Variables Used

Length of Telescope - (Measured in Meter) - Length of Telescope is the distance from the eyepiece to the objective lens in a microscope or telescope, affecting magnification and resolution.
Focal Length of Objective - (Measured in Meter) - Focal Length of Objective is the distance between the objective lens and the point where the object is in focus in a microscope or telescope.
Least Distance of Distinct Vision - (Measured in Meter) - Least Distance of Distinct Vision is the minimum distance at which the human eye can distinguish two points as separate in microscopes and telescopes.
Focal Length of Eyepiece - (Measured in Meter) - Focal Length of Eyepiece is the distance between the eyepiece lens and the point where the image is formed in a microscope or telescope.

STEP 1: Convert Input(s) to Base Unit

Focal Length of Objective: 100 Centimeter --> 1 Meter (Check conversion here)
Least Distance of Distinct Vision: 25 Centimeter --> 0.25 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

L_telescope = f_o+(D*f_e)/(D+f_e) --> 1+(0.25*0.04)/(0.25+0.04)

Evaluating ... ...

L_telescope = 1.03448275862069

STEP 3: Convert Result to Output's Unit

1.03448275862069 Meter -->103.448275862069 Centimeter (Check conversion here)

FINAL ANSWER

103.448275862069 ≈ 103.4483 Centimeter <-- Length of Telescope

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.

How to Calculate Length of Astronomical Telescope?

Length of Astronomical Telescope calculator uses Length of Telescope = Focal Length of Objective+(Least Distance of Distinct Vision*Focal Length of Eyepiece)/(Least Distance of Distinct Vision+Focal Length of Eyepiece) to calculate the Length of Telescope, Length of Astronomical Telescope formula is defined as the total distance between the objective and eyepiece lenses, which determines the overall length of the telescope, affecting its magnification power and ability to observe distant objects in the universe. Length of Telescope is denoted by L_telescope symbol.

How to calculate Length of Astronomical Telescope using this online calculator? To use this online calculator for Length of Astronomical Telescope, enter Focal Length of Objective (f_o), Least Distance of Distinct Vision (D) & Focal Length of Eyepiece (f_e) and hit the calculate button. Here is how the Length of Astronomical Telescope calculation can be explained with given input values -> 10344.83 = 1+(0.25*0.04)/(0.25+0.04).

FAQ

What is Length of Astronomical Telescope?

Length of Astronomical Telescope formula is defined as the total distance between the objective and eyepiece lenses, which determines the overall length of the telescope, affecting its magnification power and ability to observe distant objects in the universe and is represented as L_telescope = f_o+(D*f_e)/(D+f_e) or Length of Telescope = Focal Length of Objective+(Least Distance of Distinct Vision*Focal Length of Eyepiece)/(Least Distance of Distinct Vision+Focal Length of Eyepiece). Focal Length of Objective is the distance between the objective lens and the point where the object is in focus in a microscope or telescope, Least Distance of Distinct Vision is the minimum distance at which the human eye can distinguish two points as separate in microscopes and telescopes & Focal Length of Eyepiece is the distance between the eyepiece lens and the point where the image is formed in a microscope or telescope.

How to calculate Length of Astronomical Telescope?

Length of Astronomical Telescope formula is defined as the total distance between the objective and eyepiece lenses, which determines the overall length of the telescope, affecting its magnification power and ability to observe distant objects in the universe is calculated using Length of Telescope = Focal Length of Objective+(Least Distance of Distinct Vision*Focal Length of Eyepiece)/(Least Distance of Distinct Vision+Focal Length of Eyepiece). To calculate Length of Astronomical Telescope, you need Focal Length of Objective (f_o), Least Distance of Distinct Vision (D) & Focal Length of Eyepiece (f_e). With our tool, you need to enter the respective value for Focal Length of Objective, Least Distance of Distinct Vision & Focal Length of Eyepiece and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
