488.0 nm (wavelength of an argon laser)

Calculate the frequency of each of the following wavelengths of electromagnetic radiation. 488.0 nm (wavelength of an argon laser) 488.0 nm (wavelength of an argon laser) Express your answer using three significant figures.

ν1 = s−1  
Part B 503 nm (wavelength of maximum solar radiation) Express your answer using three significant figures.
ν2 =   s−1  
Part C 337.1 nm (wavelength of a nitrogen laser) Express your answer using three significant figures.
ν3 =   s−1  

Answer

A) lambda = 488.0 nm = 4.880*10^-7 m use: f = c/lambda =(3.0*10^8 m/s)/(4.880*10^-7 m) = 6.148*10^14 Hz Answer: 6.148*10^14 s-1 B) lambda = 503 nm = 5.03*10^-7 m m use: f = c/lambda =(3.0*10^8 m/s)/(5.03*10^-7 m) = 5.96*10^14 Hz Answer: 5.96*10^14 s-1 C) lambda = 337.1 nm = 3.371*10^-7 m use: f = c/lambda =(3.0*10^8 m/s)/(3.371*10^-7 m) = 8.899*10^14 Hz

Answer: 8.899*10^14 s-1
