1. Break Down the Problem

We need to identify which type of electromagnetic (EM) wave has the highest energy and frequency, and is also used for detecting cancer cells.

2. Relevant Concepts

• Energy and Frequency Relationship: The energy $E$ of an electromagnetic wave is related to its frequency $f$ by the formula: $E = h f$ where $h$ is Planck's constant.
• Types of EM Waves: The order of EM waves from lowest to highest energy and frequency is as follows:
  • Radio-waves
  • Microwaves
  • Infrared
  • Visible light
  • Ultraviolet
  • X-rays
  • Gamma rays

3. Analysis and Detail

• Radio-waves: Low energy and frequency.
• Microwaves: Higher than radio but still not enough for cancer detection.
• Infrared: Higher energy, mainly used for thermal detection.
• X-rays: Significant energy level used in medical imaging.
• Gamma rays: Highest energy waves, frequently used in cancer treatment (radiation therapy) and diagnostic imaging.

4. Verify and Summarize

Among the options, gamma rays definitively possess the highest energy and frequency. They are critical in medical applications, especially in the detection and treatment of cancer cells.

Final Answer

The EM wave that has the highest energy, frequency, and also discovers cancer cells is Gamma rays.
