Possible that a fabric can be used as a diffraction grating

Click For Summary
SUMMARY

Fabrics can indeed function as diffraction gratings when the spacing between their threads is on the order of a micron. This allows for noticeable diffraction of light in the visible spectrum, similar to traditional diffraction gratings. The discussion also touches on the concept of sound diffraction, explaining how sound waves can travel and be heard over distances, such as a neighbor's voice being audible from another house.

PREREQUISITES
  • Understanding of diffraction principles
  • Knowledge of light wave behavior
  • Familiarity with sound wave propagation
  • Basic concepts of fabric structure and thread spacing
NEXT STEPS
  • Research the physics of diffraction gratings
  • Explore the relationship between thread spacing and light diffraction
  • Study sound wave propagation and diffraction effects
  • Investigate applications of fabrics in optical technologies
USEFUL FOR

Physicists, materials scientists, audio engineers, and anyone interested in the interaction of light and sound with various materials.

Is it possible that a fabric can be used as a diffraction grating where in the space between strands of threads is a small fraction of a millimeter?

My answer is yes. does it mean that the light can be bended due to this? I mean how come?

My answer is yes
You are right.

does it mean that the light can be bended due to this? I mean how come?
In the exact same way that a diffraction grating (transmission) does. As long as the spacing is of order a micron, you will have noticeable diffraction in the visible range.

One more thing... How is it possible for those "sound waves" be heard by a person even if he's in a different house... I mean, yup, by diffraction, one can hear your neighbor shouting at your house? How would that sound travel.. in order to hear it?
