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 18.2THz. Calculate the wavelength of the infrared radiation.

Wavelength = 16.48 µm

Explanation:

As we know ...

Wavelength = Speed of light / Frequency

Wavelength = 3 x 10^8 / 18.2 x 10^12

Wavelength = 0.1648 x 10^-4 m = 16.48 µm
