Determining Target Thickness from Area Density

Click For Summary
SUMMARY

The discussion focuses on determining the thickness of a target material using its area density, specifically an example of 70 micrograms/cm². It concludes that knowing the material's density (in kg/m³) allows for the calculation of thickness using the relationship between area density and density. The participant successfully identifies the necessary equation to perform this calculation, emphasizing the importance of unit analysis in solving the problem.

PREREQUISITES
  • Understanding of area density and its units (e.g., micrograms/cm²)
  • Knowledge of material density and its units (e.g., kg/m³)
  • Familiarity with basic physics equations
  • Ability to perform unit conversions
NEXT STEPS
  • Research the relationship between area density and material thickness
  • Study the concept of density in various materials
  • Learn about unit conversion techniques in physics
  • Explore practical applications of area density in experimental physics
USEFUL FOR

Experimental physicists, materials scientists, and students studying physics who are interested in understanding the relationship between area density and material thickness.

Ok I am studying experimental physics and I wondering if you can determine the thickness of a target if you only know the area density. For example if you have a target of 70 micrograms/cm^2 can you determine the thickness from just this information ? I have tried to find equations but cannot find a way to do it, so is it possible ?
 
Physics news on Phys.org
If you know what the material is you should be able to look up it's density (kg/m^3)
then you can determine the thickness
 
Ahh ok I have found the equation thanks for helping.

Also I guess I should know that all I have to do is look at the units to determine how to find the thickness.

I must be not thinking straight today !

Cheers
