X-rays have wavelengths of approximately:
A10 to 100 nm
B100 to 700 nm
C700 to 1000 nm
D0.01 to 10 nm
Answer & Solution
Correct answer: D. 0.01 to 10 nm
1. Different regions of the electromagnetic spectrum are set apart by wavelength.
2. X-rays exhibit wavelengths of approximately 0.01 to 10 nanometres.
3. Those are far shorter than visible light, which is why they penetrate soft tissue.
4. Dorothy Crowfoot Hodgkin used them to work out molecular structures.
