Cobalt−60 is a radioactive isotope used to treat cancers of the brain and other tissues. A gamma ray emitted by an atom of this isotope has an energy of 5.90 MeV (million electron volts; 1 eV = 1.602 × 10−19 J). What is the frequency (in Hz) and the wavelength (in m) of this gamma ray? Enter your answers in scientific notation. Frequency: × 10 Hz Wavelength: × 10 m

BIOPHYSICS Cobalt-60 (60Co), is a synthetic radioactive isotope of cobalt with a half-life of 5.2713 years. It is an isotope that emits gamma rays essential to the medical community for cancer treatments, as well as sterilization of medical devices. Cobalt-60 is used as a radiation source for medical radiotherapy where it is used in cancer treatment to control or kill malignant cells. Cobalt-60 is used as the radiation source in Gamma Knife equipment that enables non-surgical treatment of brain tumors....
