What is the meaning of the height of collimation?
This term is used in surveying. 'Height of collimation' means height of instrument.Generally this term is used while doing levelling i.e. Measuring elevation of given point.
What is the height of collimation?
The height of collimation is the height of the line of sight. It is the vertical distance of the horizontal plane through a telescope.
Should telescopes go inside or outside?
Telescopes are used inside
What is a type of collimation device?
diaphragm
What are reflecting and refracting telescopes designed for?
Light is found by reflecting telescopes and refracting telescopes are used to dected sound
Who used a telescopes to make discoveries about planets?
Telescopes are instruments used by astronomers. The first person to do this was Galileo.
What are the largest telescopes used for observations in the visible region of the spectrum?
The largest telescopes that use visible light are reflector telescopes.
How are telescopes used in astronomy?
Telescopes are used to see things that are far away from earth. Using telescopes we can see things that are millions of miles away. Most of the telescopes are on Earth but some of them are in space such as the Hubble Space Telescope.
What are the largest telescopes used for observations in the visible region of the spectrum called?
The largest telescopes that use visible light are reflector telescopes.
What kinds of telescopes are used to see stars in visible light?
Refracting telescopes and reflecting telescopes are commonly used to observe stars in visible light. These telescopes utilize lenses or mirrors to gather and focus light, allowing astronomers to view stars with clarity and detail.
What technology has been used to investigate Saturn?
Ground telescopes and orbital satellite telescopes.
How can avoid error in spirit leveling collimation error refraction error division of staff?
Collimation Error: Collimation error occurs when the collimation axis is not truly horizontal when the instrument is level. The effect is illustrated in the sketch below, where the collimation axis is tilted with respect to the horizontal by an angle α: Figure ( ) In this particular example, the effect is to read too high on the staff. For a typical collimation error of 20", over a sight length of 50m the effect is 5mm. If the sight lengths for back sight and foresight are equal, the linear effect is the same for both readings. When the height difference is calculated, this effect cancels: δh = (b + s. α) - (f + s. α) = b - f That is, the effect of the collimation error is eliminated if sight lengths are kept equal.
