Electromagnetic radiation travels through vacuum at a speed of _______...
The Speed of Electromagnetic Radiation in a Vacuum
Electromagnetic radiation refers to the propagation of energy through electric and magnetic fields. It includes a wide range of wavelengths, from radio waves to gamma rays. One of the fundamental properties of electromagnetic radiation is its speed, which is constant in a vacuum.
Speed of Light
The speed of electromagnetic radiation in a vacuum is equivalent to the speed of light. This speed is denoted by the symbol 'c' and is approximately 3.00 x 10^8 meters per second.
Constant Speed in a Vacuum
Electromagnetic radiation, including visible light, travels through a vacuum at a constant speed of 3.00 x 10^8 m/s. This speed is the same for all wavelengths of electromagnetic radiation.
Independence of Speed on Wavelength
Option 'B' suggests that the speed of electromagnetic radiation depends on its wavelength. However, this is incorrect. The speed of electromagnetic radiation is independent of its wavelength. All electromagnetic waves, regardless of their wavelength, travel at the speed of light in a vacuum.
Option 'C' is Correct
Therefore, the correct answer is option 'C' - 3.00 x 10^8 m/s, which represents the constant speed of electromagnetic radiation in a vacuum. This speed is commonly rounded to 186,000 miles per second for easier understanding.
Conclusion
In summary, electromagnetic radiation, including visible light, travels through a vacuum at a constant speed of 3.00 x 10^8 m/s. This speed is the same for all wavelengths of electromagnetic radiation and is denoted as the speed of light.
