The speed of light is always the same, as long as the light stays in vacuum
or in the material substance it's in.
The speed of the source generating the light, or the speed of the person
who's measuring the light, has no effect on the light's speed. It will always
measure the same number.
That means:
-- If a rocket is in space, flying toward you at half the speed of light, and the astronaut aboard shines a flashlight at you, and
-- If you strap a jet-pack on your back and fly toward the rocket at half the speed of light, and
-- If you measure the speed of the light from his flashlight as it shines past you,
-- You'll measure the same speed of light as if you and the astronaut were both standing still.
It can't be . . . But it is. It's been confirmed in thousands of experiments during
the past 100 years.
What else can I help you with?
Does the color of a laser affect the velocity of a light wave projected by the laser?
Colors are determined by the wavelengths but all wavelengths travel at the same speed. So no, colors do not affect the velocity of light.
Does the color of the laser affect the velocity of the light wave projected by the laser?
No, velocity and color are independent. Color is determined by frequency, and speed is determined by what material the light is traveling through.
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.
Why a change in speed of the rover might not effect its velocity?
A change in speed may not affect the velocity of the rover if the change in speed happens in a direction perpendicular to the current velocity vector. Velocity is a vector quantity that includes both speed and direction, so changes in speed alone may not affect the overall velocity if the direction remains constant.
What is the velocity of car light?
The velocity of light coming from a cars lights will be the speed of light C in the substance in front of the lights. It wont be the speed of light+the speed of the car however.
Which factors affect the velocity of light?
The speed of light in a vacuum is constant. Otherwise, the speed of light will depend on what materials it travels through. For example, the speed of light in air is similar to the speed of light in a vacuum; in water, it is quite a bit slower.
What effect does a plane mirror have on the speed of light?
A mirror has no effect on the speed of light, but it has a radical effect on thevelocity of the wavefront, because it reverses the direction of the normalcomponent of the velocity.
what is the velocity of light?
The velocity of light coming from a cars lights will be the speed of light C in the substance in front of the lights. It wont be the speed of light+the speed of the car however.
Does the color of a laser affect the velocity of the light waves projected by the laser?
does the color of a lease affect the velocity of the light waves projected by the laser?
Does friction affect speed or velocity?
Friction can affect an object's speed by reducing it over time, as it acts in the opposite direction to the object's motion. However, friction does not directly affect an object's velocity which is a vector quantity that includes both speed and direction.
What factors could affect the velocity of a moving object but not the speed?
None, velocity is the speed at which something moves, they are the same thing
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.
