A recent study found that electrons having energies between 3.25 eV and 20.3 eV can cause breaks in a DNA molecule, even though they do not ionize the molecule. If a single photon were to transfer its energy to a single electron, what range of light wavelengths could cause DNA breaks?
a) minimum wavelength
b) maximum wavelength

Consider an electron in the first Bohr orbit of a hydrogen atom, (a) What is The radius (in meters) of this orbit? (b) What is the total energy (in eV) of the electron in this orbit? (c) How much energy is required to ionize a hydrogen atom when the ..
In designing rotating space stations to provide for artificial-gravity environments, one of the constraints that must be considered is motion sickness. Studies have shown that the negative effects of motion sickness begin to appear when the rotati..
