A. What is the frequency of a photon with a wavelength of 8.35 multiplied by 105 m? (The speed of light in a vacuum is 2.998 multiplied by 108 m/s. Planck's constant is 6.626 multiplied by 1034 J·s.)
B. What is the wavelength of a photon with a frequency of 6.00 multiplied by 1014 s1? (The speed of light in a vacuum is 2.998 multiplied by 108 m/s. Planck's constant is 6.626 multiplied by 1034 J·s.)

A. What is the frequency of a photon with a wavelength of 8.35 multiplied by 10^5 m? (The speed of light in a vacuum is 2.998 multiplied by 108 m/s. Planck's constant is 6.626 multiplied by 10^34 J·s.)
B. What is the wavelength of a photon with a frequency of 6.00 multiplied by 10^14 s1? (The speed of light in a vacuum is 2.998 multiplied by 10^8 m/s. Planck's constant is 6.626 multiplied by 10^34 J·s.) 
c = frequency*wavelength works both of them.
