Answer 23

Ok so you've got gamma rays, x-rays, UV rays, visible light (which we can see) , IR (infared) microwave, and radio waves. The gamma rays are the most dangerous since they have the greatest frequency and shortest wavelength.
Radio waves are the least harmful to humans since they have the lowest frequency and longest wavelengths.
The stronger the frequency the more harmful. Wavelength and frequency are inversely related.
