Question

What is the wavelength and frequency of cosmic rays

Answer 1

wavelength=

Cosmic-rays as a radiation of extremely high frequency and penetrating power that originates in outer space and consists partly of high-energy atomic nuclei. ... X-rays have smaller wavelengths and therefore higher energy than ultraviolet waves. We usually talk about X-rays in terms of their energy rather than wavelength.

frequency=

The highest energy cosmic rays measured to date have had more than 1020 eV,
