What word means how bright a star appears?
The word you are looking for is "apparent magnitude," which is a measure of how bright a star appears to an observer on Earth. It is based on the star's intrinsic brightness and its distance from Earth.
Which word means the same as an observer?
watcher
What is an apparent brightness?
An apparent brightness is the brightness of a star as measured by an observer.
How is the apparent size of an object affected by its distance from the observer?
The apparent size of an object decreases as it moves farther away from the observer. This is because the angle that the object subtends at the observer's eye decreases as the distance increases, making the object appear smaller.
How the apparent motion of a object depend on the observer motion?
The apparent motion of an object can vary depending on the motion of the observer. This is due to the concept of relative motion, where the perception of an object's movement is influenced by the observer's own motion. For example, if the observer is moving towards an object, the object may appear to move faster than if the observer is stationary.
What are Manifested actions?
A "manifest action" is an action that is readily apparent to an observer.
How does apparent motion of an object depend on the observer and in motion?
The apparent motion of an object depends on both the observer's perspective and the motion of the object itself. As the observer moves, their angle of view and distance from the object change, altering how the object appears to move relative to them. In addition, the speed and direction of the object's actual motion will impact how it appears to move to the observer.
Motion is described with respect to a what?
With respect to a state of rest or apparent rest.
How to calculate apparent frequency the source is ahead and observer is behind both moving the same direction?
The apparent frequency does not depend on who is in front.
What is the name of the apparent change in a pitch of a moving source called?
The apparent change in pitch of a moving sound source is called the Doppler effect. It describes how the frequency of the sound waves perceived by an observer changes as the source of the waves moves relative to the observer.
Is there a prefix in the word apparent?
No, there is no prefix in the word apparent.
Why is the word emerge in emergency?
Emergency means an unforeseen occurrence requiring immediate action. Emerge means to come into view or to become apparent. The word emergency has the word emerge embedded in it because it has its etymology in the word emerge - An emergency is something that quickly emerges, or becomes apparent, and needs acting on.
