Answer :
Out of The following speed is the same for all kinds of electromagnetic waves.
Electromagnetic waves travel at the same speed through space. That speed, also known as the speed of light is approximately 300 million meters per moment which are 3.0 x 108 m/s...Although all electromagnetic waves travel at the same speed over space, they may vary in their wavelengths, frequencies, and energy levels. Wavelength is the distance between comparing focuses of adjacent waves. Frequencies of electromagnetic waves run from thousands of waves per second to trillions of waves per second. The energy of electromagnetic waves depends on their frequency. Low-frequency waves have small energy and are ordinarily safe. High-frequency waves have a lot of energy.
