Explanation:
The element symbol for oxygen<span> is O and its atomic number is 8. The mass numbers for oxygen must be 8 + 8 = 16; 8 + 9 = 17; 8 + 10 = 18</span>
The relationship of wavelength and frequency of a wave is v=f*λ. f means the frequency, v means the speed, λ means the wavelength. So the answer is 9.67*10^(-7).
