Question

how does the speed of visible light compare with the speed of gamma rays, when both speeds are measured in a vacuum?

no answer can be determined from the information given.

the speed of gamma rays is greater.

the speed of visible light is greater.

the speeds are the same.

Explanation:

Visible light and gamma rays are both electromagnetic waves. In a vacuum, all electromagnetic waves travel at the same speed, which is the speed of light (\(c = 3\times10^{8}\ m/s\)).

Answer:

The speeds are the same.
