Electromagnetic radiation travels through vacuum at a speed of __________ m/s.
186,000
3.00 × 108
10,000
It depends on wavelength
The speed of light (electromagnetic radiation) through vacuum has a constant value of 3.00 x 108m/s and is independent of the wavelength in vacuum.
In vacuum all types of electromagnetic radiations, regardless of wavelength, travel at the same speed.
In the vacuum, all types of electromagnetic radiations regardless of wavelength travel at the same speed.
