The sun produces its own light when it transforms hydrogen into helium. The moon gets its light from the sun. It doesn't produce light. The brightness that we see on the moon is a reflection of the sunlight.
the brightness of a star usually means how close it is to earth and the colour means how hot it is. blue/white being the hottest and colours like red yellow and orange being not as hot.
An apparent brightness is the brightness of a star as measured by an observer.
It depends on what the sentence is: The brightness of the sun is blinding. The word brightness would be an adjective.
I will help adjust the brightness of your TV screen.
The 100W light bulb is brighter than the 60W light bulb. The difference in brightness is 40 watts.
No, the brightness ratio is the numerical difference between the brightest and darkest light levels emitted by a display. It is a measure of the display's dynamic range.
Yes, there may be a difference in bulb brightness depending on factors like the voltage applied, resistance in the circuit, and the type of bulb used. These factors can affect the current flowing through the bulb, ultimately impacting its brightness.
High contrast refers to a large difference in brightness between the lightest and darkest parts of an image, resulting in strong visual impact and sharp edges. Low contrast, on the other hand, has a smaller difference in brightness, creating a softer, more muted look with less distinct separation between tones.
The brightness of the colors used
Tint is a color's brightness or dullness, while shade creates shadows within a painting.
The difference between apparent brightness and luminosity is that apparent brightness means that a star may appear to be bright, but only looks bright because of the relatively closeness a star is to earth. Luminosity is used by astronomers and refers to the power output of a star. Apparent Brightness means a star may appear to be very bright but only look that way because it is relatively close to Earth. Luminosity just refers to the power output of a star.

amplitude
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.
