Question

Electromagnetic waves used in a diagnostic tool in medicine have a wavelength range

• A. \(1\ \text{nm}\) to \(10^{-3}\ \text{nm}\)
• B. \(400\ \text{nm}\) to \(1\ \text{nm}\)
• C. \(1\ \text{mm}\) to \(700\ \text{nm}\)
• D. \(0.1\ \text{m}\) to \(1\ \text{mm}\)

Hint:

Remember the sequence of electromagnetic waves: \[ \text{Radio} \rightarrow \text{Microwave} \rightarrow \text{Infrared} \rightarrow \text{Visible} \rightarrow \text{Ultraviolet} \rightarrow \text{X-rays} \rightarrow \gamma\text{-rays} \] Medical diagnosis generally uses X-rays having wavelengths from \[ 1\ \text{nm} \text{ to } 10^{-3}\ \text{nm}. \]
