This is a tricky question, because we know that different frequencies of light does travel with different speeds through mediums, so the answer would depend on what frequency of laser light you're talking about, and also agreeing on what you mean by "sunlight", since "sunlight" are light containing all possible frequencies of visible light, ultraviolet and infrared, etc.

Different frequencies of light do travel at different speeds thru a medium (in this case air), but the difference would be so insubstantial in this case that it doesn't matter.
Sunlight and laser light would, for all intents and purposes, travel at the same speed at sea level.

To clear up the confusion, a light beam will propagate (as a whole) at different speeds through a medium depending on its frequency. This is referred to as its "group velocity" and it can be anywhere from zero to c. When you read about people "stopping" a beam of light, they mean stopping the group velocity.
The phase velocity, or the speed of individual photons, is always c, period. The group of photons can move more slowly than the individual photons because the individual photons maybe be absorbed and re-emitted by the material through which it propagates with some delay time in between.

No, it does not. Light travels at c~ 3x10^8 m/s regardless of the medium or reference frame. The wavelength and frequency of the laser light and sunlight would be different, but the light from both sources would be travelling at c.

I'm in agreement with the person who said that light travels at the speed of light.

No. Light travels at the speed of light, no matter what kind of light it is.

depends on the frequency and wavelength of the particular laser, i would say that sunlight maybe faster because its in the visible spectrum and travels at 300,000,000 meters per sec. goodluck!!!, ................ p.s some laser beams travel at 3xthe speed of light but travel only a short distance.

No bcoz sun light doesnt require a medium while laser requires.

All lights have the same speed .

over 186,000 mile each 2d. It takes approximately 8 minutes for mild to prevail in Earth from the sunlight. At 186,000 miles according to 2d. At that velocity you ought to shuttle around the Earths' equator 40 six cases in one 2d!
