    The color is orange.

    To find the frequency, we divide the speed of light (c) which is

    2.998 * 10**8 meters per second by the wavelength, here given as

    6.2 * 10**-7 meter. When we do the division we obtain

    4.835 * 10**14 cycles per second, or Hertz, as the frequency.

    Hope this answers your question.
