# When wavelength is smaller than 1pm

Hi all,

Higher end of electromagnetic spectrum is γ rays around 1pm (300EHz). What are the characteristics of frequencies having smaller wavelength than γ rays ?

What are the characteristics of signals that has wavelength at Planck scale?

Hi all,
What are the characteristics of frequencies having smaller wavelength than γ rays ?

Gamma rays by definition include all wavelengths below 10 picometers. There are no wavelengths "smaller" than gamma rays because no matter how small you get, they are still called gamma rays.

What are the characteristics...

Gamma rays have enough energy to be ionizing (rip electrons off atoms), so they are damaging to biological tissue. Additionally, at high enough energy, a gamma particle turns into an electron-positron pair, turning its energy into the mass of these particles.
