Wavelength and Frequency

Q. Infrared radiation from young stars can pass through the heavy dust clouds surrounding them, allowing astronomers here on earth to study the earliest stages of star formation, before a star begins to emit visible light. Suppose an infrared telescope is tuned to detect infrared radiation with a frequency of 6.43THz. Calculate the wavelength of the infrared radiation. Be sure your answer has the correct number of significant digits.
