There is no average velocity of light. Within a given medium, the velocity of light is fixed and absolute. In a vacuum, it is approximately 3.0 x 108 m/s, or 186,000 miles per second. It would be somewhat slower through denser media like water and glass.

What is the magnitude of average velocity?
Not directly. acceleration is the rate at which velocity changes, but unless near light-speed the only reason velocity would cause any difference to acceleration would be due to forces which are proportional to velocity, such as drag or friction. Near the speed of light time bends so a body would, compared to the rest of the universe, appear to decelerate so as to reach a maximum velocity of the speed of light.
When average velocity and average speed is equal?
For the instantaneous value of average velocity, average speed and average velocity are equal.
How is velocity different from average speeed?
Velocity is speed and its direction. Average velocity is average speed and its direction.
When is the average velocity equal to average of velocity for an object?
Always.
What is average velocity?
Average velocity is def.ined as the ratio of total displacement to total time taken.
What is the velocity of light in meters?
the velocity of light is 300000000 m/s
Does average velocity have a direction associated with it?
The term "velocity", as used in physics, DOES have an associated direction. Most derived terms, such as "average velocity", also do.
Does average velocity and average speed have the same number?
velocity is a vector and speed is scalar. Velocity has magnitude and directions, with magnitude being speed. The magnitude of average velocity and average speed is the same.
What is the best definition of velocity?
The speed of something in a given direction.
What is the relationship between average velocity and instantaneous velocity?
The average velocity over an time interval is the average of the instantaneous velocities for all instants over that period. Conversely, as the time interval is reduced, the average velocity comes closer and closer to the instantaneous velocity.
What is average velocity's definition?
Average Velocity is displacement over total time.
Does Light have a speed or a velocity speed of light or velocity of light?
Light travels at the speed of light. There is no general velocity of light because velocity is a vector quantity, it also contains a direction and there is no preferred direction for light rays in general. Another answer: The speed of light has been calculated to be 186,000 miles per second.
