Question
The wavelength of the X-ray is measured by:
Options
- A
Diffraction
- B
Interference
- C
Reflection
- D
All of these
Explanation
By diffraction, x-ray wavelength is found.
By diffraction, x-ray wavelength is found.
Interference, is the net effect of the combination of two or more wave trains moving on intersecting or coincident paths. The effect is that of the addition of the amplitudes of the individual waves at each point affected by more than one wave.
Reflection is when light bounces off an object.
A is the only answer hence this option is incorrect.
