Electromagnetic energy (of which light is one type) with a frequency of 1,000,000,000,000,000 Hertz, or 1015 Hertz or 1 petaHertz has a wavelength of 2.995 x 10-5 cm. That puts the radiation at the top edge of the visible spectrum or in the near ultraviolet region. Better get out your sunblock just in case. You'll find links below to a "converter" to change wavelength to frequency and vice versa, and also to an abbreviated chart of the electromagnetic spectrum so you can see where stuff is on it. Now you can post answers to questions like this one!
