Caculate the wavelength of electromagnetic radiation having a frequency of 1.37 X 10^15 Hz

the wavelength of electromagnetic radiation having a frequency of 1.37 * 10¹⁵ is 2.18 * 10⁻⁷

calculation

wavelength = speed of light / frequency

speed of light = 3.0 * 10⁸ m/sec

frequency = 1.37 * 10¹⁵ hz = 1.37 * 10¹⁵ 1/sec

wavelength = (3.0 * 10⁸ m/sec) / (1.37 * 10¹⁵ 1/sec)

= 2.18 * 10 ⁻⁷ m
