Question

blue green light has a frequency of about 6.8 x1014 Hz. use the relationship c=f to findthe wavelength of this light in air. (the answer is 441 nm or 4.41 x 10-7 m) how does this wavelength compare with the size of anatom, which is about 10-10 m? (wavelength/size of atom) blue green light has a frequency of about 6.8 x1014 Hz. use the relationship c=f to findthe wavelength of this light in air. (the answer is 441 nm or 4.41 x 10-7 m) how does this wavelength compare with the size of anatom, which is about 10-10 m? (wavelength/size of atom)

Explanation / Answer

frequency f = 6.8 x 1014 Hz
the wavelength of this light in air = c / f where c = 3 * 10 ^ 8 m / s plug the values weget = 0.4411 * 10 ^ -6 m                                     = 441.1 * 10 ^ -9 m                                     = 441.1 nm (b). wavelength / size of atom = 441.1 * 10 ^ -9 / ( 10^-10 m)                                             = 4411
