What is the frequency of radiation that has a wavelength of 0.952 µm?

What is the frequency of highly energetic ultraviolet radiation that has a wavelength of 128 nm? The speed of?

  • Answer:

    There's a short cut you can use. 300,000 / wavelength (in nm) = Frequency (in THz) 300,000 / Frequency (in THz) = wavelength (in nm) This works infar-red, ultra-violet and visible light. 300000/128= 2343.75 THz or 2.34375*10^15 Hz.

wavelength = 128 nm = 128 * 10^-9 m speed of light = speed of wave, c = 3*10^8 m/s we know that, speed of wave, c = frequency* wavelength so, frequency = speed of wave / wavelength = (3*10^8) / (128*10^-9) = 2.34 * 10^15 Hz
