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

Chem help pleaseee ! A) what is the frequency of radiation that has a wavelength of 10 micrometers about......?

  • The size of a bacterium. B) what is the wavelength of radiation that has a frequency of 5.50x10^14 S^-1 ? C) would the radiations in part a or part b be visible to the human eye. D) what distance does electromagnectic radiation travel in 50.0 microseconds?

  • Answer:

    A c = n λ 3e8 = n *1 e- 6 n = 3.e+14 Hz ( gamma rays ) B c = n λ 3e8 = 5.54e14 λ λ = 5.42 e-7 m C Gamma rays invisible to human eye. D S = ct = 3e8*50 e-6 = 1.5e+4 m ===================

I wonder what planet Pearlsaw is from, where 10 μm photons are gamma rays.  10 μm is well into the infrared (visible light is about 0.8-0.4 μm). f = c/λ = 3e8/1e-5 = 3e13/sec No, it's quite invisible.  It's in the far IR. d = 3e8 m/s * 5e-5 sec, you do the math for once.
