Question 1.
What does UV-Visible Spectroscopy measure?
Show hintHide hint
Think about the types of light involved.
Question 2.
What does X-ray Diffraction help to identify?
Show hintHide hint
Consider what happens to X-rays when they hit a solid material.
3Question 3.
What is the main purpose of UV-Visible Spectroscopy?
- To measure electrical conductivity
- To measure absorption of light
- To measure thermal properties
Show hintHide hint
Think about light’s role in the spectral analysis.
4Question 4.
Raman Spectroscopy primarily provides information about what aspect of materials?
- True
- False
Show hintHide hint
Consider the significance of vibrations in structural analyses.
Question 5.
You have a sample of gold nanoparticles that change color from red to blue as they grow. Using UV-Vis data, how would you determine the concentration of nanoparticles in solution?
Show hintHide hint
Consider the relationship between light absorption and concentration.
Question 6.
A diffraction pattern shows a peak broadening in XRD analysis. How would you apply the Scherrer equation to estimate the change in particle size compared to an earlier measurement?
Show hintHide hint
Think about how peak width relates to size within XRD.
