8. In photo-chemical process, the rays which provide better resolution are __________
a) Infrared
b) Visible Light
c) UV light
d) X-rays
View Answer

Answer: d
Explanation: Since X-ray have much shorter wavelength comparing to the visible light, they are considered a promising option to provide better resolution in photo-chemical processes such as semiconductor etching etc.

9. The process of using X-rays for identifying atomic structure is called _________
a) X-ray Radiography
b) X-ray Crystallography
c) X-ray Diagnosis
d) X-ray Structure Identification
View Answer

Answer: b
Explanation: X-ray crystallography is used to identify the molecular and atomic structure of the crystal. The crystal diffracts the incident X-ray beam. By measuring the intensities and angle of these diffracted beams, the molecular structure of the crystal can be evaluated.
