MCQ
The $X$-ray beam coming from the $X$-rays tube will be
- AMonochromatic
- BDichromatic
- ✓Having all wavelengths greater than a certain minimum wavelength
- DHaving all wavelengths between a minimum and maximum wavelengths
✓
Answer
Correct option: C.
Having all wavelengths greater than a certain minimum wavelength
c
(c)
(c)
Only the minimum wavelength is fixed in the case of an $X$-ray from $X$-ray tube. In this case $X$-rays are formed from emission by a substance and all possible transitions need to be accounted for. The only limit is the maximum energy supplied to material by incident light which depends on incident light.
