Question

Name the electromagnetic wave used (i) in radar, (ii) in eye surgery, and (iii) as a diagnostic tool in medicine. Write their wavelength range also.

Hint:

Different regions of the electromagnetic spectrum are used for various applications based on their energy and penetration ability: microwaves for communication, UV for precision surgical procedures, and X-rays for imaging inside the body.

Answer 1

\begin{center}\begin{tabular}{|c|l|l|}\hlineApplication & Electromagnetic Wave Employed & Wavelength Spectrum
\hline(i) Radar Detection & Microwaves & \( 1\,\text{mm} \text{ to } 1\,\text{m} \)
\hline(ii) Ophthalmic Surgery & Ultraviolet (UV) Rays & \( 10\,\text{nm} \text{ to } 400\,\text{nm} \)
\hline(iii) Medical Imaging & X-rays & \( 0.01\,\text{nm} \text{ to } 10\,\text{nm} \)
