The size of the first lens is the property of an optical telescope that determines its light-gathering or light-collecting power. Thus, the solution is option B.

## Which property of a reflecting telescope determines its light-gathering or collecting power?

The light-gathering power of a telescope is determined by the diameter of its aperture, or opening—that is, by the area of its largest or primary lens or mirror.

## What are the properties of reflecting?

In the plane, the reflection property can be stated as three theorems (Ogilvy 1990, pp. 73-77): 1.

…

Reflection Property.

both foci finite | confocal ellipses |

one focus finite | confocal parabolas |

both foci infinite | parallel lines |

## What property of a telescope influences its resolving power?

An optical telescope’s ability to resolve small details is directly related to the diameter (or aperture) of its objective (the primary lens or mirror that collects and focuses the light), and its light-gathering power is related to the area of the objective.

## What is reflection property in geometry?

In geometry, the reflexive property of congruence states that an angle, line segment, or shape is always congruent to itself.

## What is the resolution of a telescope mastering astronomy?

With adaptive optics, ground-based telescopes can achieve resolutions of 0.1 arcsecond or a little better in the infrared region of the spectrum. This impressive figure is the equivalent of the resolution that the Hubble Space Telescope achieves in the visible-light region of the spectrum.

## What is the resolving power of the telescope quizlet?

A space-based telescope can achieve a diffraction-limited angular resolution of 0.04 ′′ for red light (wavelength 670 nm ).

## What is the resolution of a telescope?

The resolution of a telescope is its ability to separate two point sources into separate images. Under ideal conditions, such as above the atmosphere where there is no turbulence (seeing), the resolving power is limited by diffraction effects.

## What is identity property?

The identity property of 1 says that any number multiplied by 1 keeps its identity. In other words, any number multiplied by 1 stays the same. The reason the number stays the same is because multiplying by 1 means we have 1 copy of the number. For example, 32×1=32.

## How are the Properties of reflection used to transform a figure?

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed). … Remember that each point of a reflected image is the same distance from the line of reflection as the corresponding point of the original figure.

## What does subtraction property mean?

The subtraction property of equality tells us that if we subtract from one side of an equation, we also must subtract from the other side of the equation to keep the equation the same. … To keep them the same, you have to do the same to both sides of the equation.
