Question

scientists discover a new electromagnetic wave with a frequency of $5.0 \times 10^{17}$ hz. based on your understanding of the electromagnetic spectrum, predict how this wave might interact with human tissue.

• it would be in the ultraviolet range and could potentially damage skin cells
• it would pass through human tissue with no effect, like radio waves
• it would be absorbed by bones only, making it useful for medical imaging
• it would be completely reflected by human tissue, causing no harm

Explanation:

1. Recall the electromagnetic spectrum: The frequency range of ultraviolet (UV) waves is approximately \(7.5\times10^{14}\) Hz to \(3\times10^{17}\) Hz. The given frequency is \(5.0\times10^{17}\) Hz, which falls within the UV range.
2. Analyze each option:

• Option 1: UV waves can damage skin cells (e.g., cause sunburn, DNA damage). This matches the properties of UV.
• Option 2: Radio waves have much lower frequencies (\(<3\times10^{11}\) Hz), so this is incorrect.
• Option 3: X - rays (higher frequency than UV) are absorbed by bones for imaging, not UV. So this is incorrect.
• Option 4: UV is not completely reflected; it is absorbed/transmitted and can cause damage. So this is incorrect.

Answer:

It would be in the ultraviolet range and could potentially damage skin cells
