What happened to the brightness of the object as you switched from 40x to the 10x to the 40 x objectves?

I saw nothing. Perhaps you could check with someone
who was actually there and watched it as it happened.

How do you evaluate the impact of termination on absenteeism?
[object Object]
When object A exerts a force on object B object B?
object B moves
If object A is inscribed in object B then what can be said about each?
Object B must be circumscribed about object A.
If object A is circumscribed about object B then what can be said about each?
.Object B must be inscribed in object A.
What is the anwers?
[object Object]
What is an non-example of absolute brightness?
Anything that is not the measure of intrinsic brightness of a celestial object.
What is difference between apparent brightness and true brightness?
Apparent brightness: how bright an object - such as a star - looks to us. True brightness: how bright such an object really is. Defined as: how bright it would look at a standard distance.
Why is the sun the brightness object in the sky?
it is beacause it is a ball of fire
According to the inverse square law of light how will the apparent brightness of an object change if its distance to us changes to one half as much as it was.?
If the brightness is 'B' right now, when the object is at a distance 'D' from your eye, then-- If the object moves closer, to only [ 1/2 D ] from you, the brightness increases to [ 4 B ].-- If the object moves farther away, to [ 2 D ] from you, the brightnesses decreases to [ 1/4 B ].
What term is used to describe a star's brightness?
It is called Vmag. This is the visual magnitude of the object. Visual magnitude is a scale used by astronomers to measure the brightness of a star or other celestial object. Visual magnitude measures only the visible light from the object. The lower the V-MAG the brighter the star. You can go to http://seasky.org/pictures/sky7b14.html to learn more.
How would you measure the brightness of light being reflected by an object?
by using a photometer
What is the function of a diaphrgam?
a diaphrgam is part of a microscope that controls brightness or light on the object you are looking at.
Magnitude is a measurement of what?
Absolute magnitude is a measure of a celestrial object brightness at a set distance. For a star, it would be the brightness at a set distance of 10 parsecs or around 32 lightyears. For a solar system object it would be the brightness from 1 AU. It takes the objects distance out of the equation so that star brightnesses can be directly compared.
Define standard candle as it is used in astronomy?
A "standard candle" in astronomy is an object whose luminosity (its true brightness, not just how bright it seems to us) can be estimated, based on characteristics of that type of object. Then its distance can be estimated from its "apparent magnitude". The stars called "Cepheid variables" are a good example. The rate at which their brightness varies is closely linked to their luminosity.
Which event happened last?
[object Object]
What do magnitude need in astronomy?
Magnitude is almost Always used when referring to Brightness of celestial object, although similar in term it can also be used in describing the brightness of the sky in the area viewing.
What is a contrast?
Contrast is the difference in light and/or gloss that hits an object distinguishable. In ocular perception of the real world, contrast is resolved by the difference in the color and brightness of the object and other.
