Yes according to most theories the velocity of light in a vacuum is constant. (In water and glass it is slower!)

What is an example of an object moving at constant speed and constant velocity?
Photon or rather light
Which of these is constant for ALL types of electromagnetic radiation in a vacuum?
Answer = Velocity Velocity is the speed of light and, the speed of light, is a constant among Electromagnetic Radiation in the vacuum of space.
What is the velocity in which the body covers equal displacements in equal intervals of ttime?
In that case, the velocity is said to be constant.
Can an object have constant velocity and but variable speed?
No. Velocity has two parts, speed and direction A constant velocity means that both the speed and the direction must be constant. So a constant velocity must have a constant speed.
Can you go around a curve with constant velocity?
Yes, it is. Trajectory also depends of direction of acceleration, not only it's magnitude. When you consider circular orbit, the agnitude of centripetal acceleration is constant, but the vector directions changes every moment to point constantly at the center.

What is speed that does not change - called?
constant

Can constant velocity be zero?
Yes. Zero velocity is a velocity; if it is always zero then it is a constant velocity.
What happens to light when it travels from air into denser?
its frequency remains constant but velocity changes.
Is the velocity of light a physical constant?
absolutely. The most important one in my bias opinion.
Is the velocity of X-rays constant?
Yes, all xrays travel at the speed of light.

In that case, the velocity is said to be constant.
What is your acceleration if you have a constant velocity?
If your velocity is constant, then your acceleration is zero.

Why areal velocity is constant in central force?
If the force is constant then this will make the velocity of the object spinning constant as well, and for the velocity to be constant all the forces must be balanced and therefore constant
