The wavelength of the red light is 700.5 nm. What is the frequency of red light?

Start by converting the wavelength from nanometers to meters. The prefix nano means 10–9.

  • 1 nm = 1 * 10^-9 m

    700.5 nm 1 m / 110^-9 nm = 700.5*10^-9 m

    f = c / wavelength

    f = (3.00 * 10^8 m/s) / (700.5 * 10^-9 m) = 4.28*10^14 Hz.

  • Use the equation c = ⅄ v. C is velocity of sunshine, ⅄ is wavelength, and v is frequency First trade the nm to m utilising the conversion factor: 1 m = 1 x 10^9 nm Them plug within the known values. Three.00 x 10^8m/s = (something wavelength comes out to be) x v clear up for v(frequency)
