What affects absolute brightness?
Brightness corresponds to amplitude of waves. Greater amplitude means greater brightness (so lower amplitude means less brightness).
What is a difference in the brightness of two lights indicative of?
It is indicative of their relative brightness, measured in candelas (units of brightness, also called candle power).
What is the brightness of Zibal?
Zeta Eridani (Zibal) is a white to white blue star in the constellation Eridanus. It has an apparent brightness of +4.80 and an absolute brightness of +1.97.
What effect would a pencil have on the brightness of a bulb?
A pencil has nothing to do with the brightness of a light bulb.
What is the device that measured Surface brightness?
A lux meter is a device that measures surface brightness.
What affects absolute brightness?
Brightness corresponds to amplitude of waves. Greater amplitude means greater brightness (so lower amplitude means less brightness).
A light waves brightness depends on the?
amplitude of the light wave!
What are some physical characteristics of the ocean?
Depth, salinity, currents, waves, and brightness.
Which of the following properties of sound is the most similar to the brightness of light?
Both sound and light waves reflect. Sound waves reflect off of objects to create an echo. Light waves reflect off of objects and point the light in another direction.
What does the amplitude of a light wave determine?
The amplitude of a light wave shows the light's brightness relative to waves of similar wavelength.
Which waves have lower frequency radar waves or visible waves?
Radar waves have a lower frequency that light waves.The frequency of a light wave is related to wavelength and speed by the equation c = »½. The color of a light wave is also determined by the frequency. The amplitude and brightness are not related to the frequency.
What are the most obvious characteristics of the ocean?
Depth, salinity, currents, waves, and brightness.
What is an apparent brightness?
An apparent brightness is the brightness of a star as measured by an observer.
What is difference between apparent brightness and absolute brightness?
Absolute Brightness: How bright a star appears at a certain distance. Apparent Brightness: The brightness of a star as seen from Earth.
A star's brightness is the brightness seen by humans on Earth. A star's brightness is its actual brightness and does not depend on where the star is viewed from.?
The brightness as seen from Earth is called the "apparent magnitude".The real brightness (defined as the apparent brightness, as seen from a standard distance) is called the "absolute magnitude".
What is the minimum brightness of a dsixl?
The brightness levels on a DSiXL can be changed to be from a brightness of 1(lowest) to a brightness of 5(highest). The screens can be dark depending on where you are.
What is a stars brightness as if it were a standard distance?
Theres `Absolute Magnitude` which is the brightness of a star at a set distance. Then there is `Apparent Magnitude` which is the apparent brightness from earth, regardless of distance.
