Question

Wavelength of radiation is 5800Angstrom. Calculate a)the wavelength in cm and nm. b)Wave number c) frequency​

Answer 1

Answer:

wave no. =0.017*10^8 m^-1

Explanation:

wave length of light=5800*10^-10 m

frequency=c/wave length

3*10^8/5800*10^-10 = 0.05*10^16

Wave no. is reciprocal of wave length

therefore, wave no. = 1/wave length = 0.017*10^8 m^-1
