Take the mass of the sun to be m_s = 1.99×1030 {rm kg}, gravitational constant to be G = 6.67×10-11 {rm N} cdot {rm m^2/kg^2}, and an acceleration due to gravity at the earth's surface to be g = 9.810 {rm m/s^2}.
Obtain the wavelength in vacuum for blue light, whose frequency is 6.253 x 1014 Hz. Express your answer in nanometers (1 nm = 10?9 m)
