(02.03 LC) Which of the following is true about the speed of light? (2 points) o It depends on the wavelength. O Ina vacuum, it is a constant value that does not depend on the observer. O It is slowest in a vacuum unless an observer is moving towards the source. O In a vacuum, it varies depending on the color of the light.

The speed of light in a vacuum is the middle speed in the universe. is the top speed in the universe. Is the same speed as other objects found in the universe. It is the bottom speed in the universe. In a medium, the speed of light is the same as the speed in a vacuum. It cannot be determined whether it is faster or slower than in vacuum. It is slower than in a vacuum. can be the same as in vacuum, depending on the index of refraction.
