What is the wavelength of a wave with a speed of 12 m/s and a period (T)
of 0.25 s? (Recall from the notes: f = 1/T)

Daughter element the new element produced along with a decay particle in a nuclear transmutation 2. half-life the substance that decays in a nuclear transmutation 3. parent element the change of one chemical element into another by nuclear decay or radioactive bombardment 4. transmutation the time required for the decay of one-half of the atoms in a sample of radioactive material
