Which side of the electromagnetic spectrum has higher frequency?

The correct choice identifies the side of the electromagnetic spectrum that possesses the highest frequency. The electromagnetic spectrum is ordered from lower frequency, longer wavelength waves to higher frequency, shorter wavelength waves.

In this case, the sequence listed in the correct answer begins with violet light, which is at the high-energy end of the visible spectrum, and continues through ultraviolet (UV), X-ray, and gamma rays. Each of these categories represents an increasing frequency:

• Violet light is one of the highest frequency colors of visible light.
• Ultraviolet rays follow, possessing even higher frequencies than visible light.
• X-rays have higher frequencies than ultraviolet light and are widely used in medical imaging.
• Gamma rays, which are emitted from radioactive materials and certain stellar phenomena, have the highest frequency of any electromagnetic radiation.

As such, this sequence highlights a progression towards higher frequencies, firmly establishing that the higher frequency radiation is indeed presented in this choice.

The other options include parts of the spectrum that do not reach the same frequencies as the sequence in the correct answer. For instance, the first choice features infrared and various colors of light, which occur at lower frequencies compared to the choices that include gamma rays and X-rays. Thus, understanding the arrangement of the electromagnetic spectrum helps in
