Electromagnetic (EM) Spectrum:
The electromagnetic (EM) spectrum is the range of all types of EM radiation arranged according to frequency or wavelength. In order of decreasing wavelength or increasing frequency these are: Radio waves radiation, Micro waves radiation, Infrared, visible light, Ultraviolet, X-rays and gamma rays.
- In a vacuum, all EM radiations travel at the same speed irrespective of the wavelength or frequency of the wave.
- Since, all EM radiations travel at the same speed, X-rays, gamma rays and UV rays will travel at the same speed.
- Since, every EM radiations have different wavelengths according to their energy level, X-rays, gamma rays and UV rays will have different wavelengths.
Hence, the correct answer is Option-2-same speed but different wavelengths.
