When comparing infrared waves to X-rays, what relationships would you expect to see in terms of wavelength, energy, frequency, and why?
Because of their inverse relationship, infrared waves will have longer wavelengths with lower frequencies than that of X-rays.
Wavelength and frequency are directly related, so infrared waves will have longer wavelengths with higher frequencies than that of X-rays.
Wavelength and frequency are inversely related, so infrared waves will have longer wavelengths with higher frequencies than that of X-rays. Their energies will be the same.
