SUMMARY

The discussion focuses on determining the ability of different frequencies to penetrate various materials. It establishes that higher and longer wavelengths are more likely to pass through objects compared to shorter wavelengths. Key factors influencing this include the Index of Refraction for visible and infrared light, as well as absorption frequencies related to molecular bonds. For microwave and radio frequencies, conductivity and material thickness are critical for approximating penetration capabilities.

PREREQUISITES
  • Understanding of Index of Refraction
  • Knowledge of absorption frequencies in materials
  • Familiarity with conductivity concepts
  • Basic principles of wavelength and frequency
NEXT STEPS
  • Research the Index of Refraction for various materials
  • Explore absorption frequency calculations for visible and infrared light
  • Study the relationship between conductivity and frequency penetration
  • Investigate the effects of material thickness on microwave and radio wave transmission
USEFUL FOR

Physicists, materials scientists, engineers working with electromagnetic waves, and anyone interested in the interaction between frequencies and materials.

I was wondering if someone could give me a formula/explanation in how to find out if a given frequency will travel through an object or some sort...

I believe higher as well as longer wavelengths have better chances of going through something than the reverse. Any ideas??

What information would you need from the object? Index of Refraction??

It depends on the materialand frequency.

For visible/infrared light and a transparent material you can work out the absorption frequncies from the bonds.

For microwave/radio you can work out an approximation from the conductivity and material thickness.
