All electromagnetic waves in a vacuum have the same
Answer Details
All electromagnetic waves in a vacuum have the same speed. This is known as the speed of light, which is approximately 3.0 x 108 meters per second. Regardless of their frequency or wavelength, all electromagnetic waves travel at this same speed in a vacuum, such as in outer space. This is a fundamental property of electromagnetic waves and is a cornerstone of modern physics.
