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 3.30 THz. Calculate the wavelength of the infrared radiation. Be sure your answer has the correct number of significant digits.
