- 0.2 to 0.3
- 0.4 to 0.5
- 1.5 to 2.1
- 6 to 7
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The Geiger-Müller counter is highly sensitive to ionizing radiation, particularly in the wavelength range of 6 to 7 angstroms (X-ray region). This is due to its high efficiency in detecting high-energy photons.
