A typical gamma ray emitted from a nucleus during radioactive decay may have an energy of 230 keV. What is its wavelength? nm Would we expect significant diffraction of this type of light when it passes through an everyday opening, like a door? Yes, as significant diffraction occurs provided the opening is at least as large as the wavelength. No, as significant diffraction occurs only when the opening is on the order of the wavelength. No, as significant diffraction occurs only when the opening is smaller than the wavelength. Yes, as significant diffraction occurs only when the opening is much larger than the wavelength.
