Question

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

विकल्प

• 1 nm to 10⁻³ nm

• 400 nm to 1 nm

• 1 mm to 700 nm

• 0.1 m to 1 mm

Answer 1

Electromagnetic waves used in a diagnostic tool in medicine have a wavelength range 1 nm to 10⁻³ nm.

Explanation:

Electromagnetic waves used in medical diagnostics are mainly X-rays. X-rays are widely used in radiography, CT scans, and dental imaging.

X-ray wavelength ≈ 10⁻³ nm to 10 nm

Diagnostic X-rays fall in 1 nm to 10⁻³ nm.

Medical imaging primarily uses X-rays (diagnostic imaging) and not visible light or radio waves.

The correct range corresponds to X-rays is 1 nm to 10⁻³ nm.
