Question

calculate wavelength and frequency of EMR whose wave number is 2000cm-1


plz solve this question and give proper answer ​

Answer 1

Answer:

I DONK KNOE THNE ANS

WAVELENGTHN =9-6/7

FREQUENCY/TIME

Answer 2

Answer:

6×10^9s^-1

Explanation:

we know that,

frequency= c×wavenumber

3×10^8m/s×2000cm^-1

3×10^8m/s×2000×10^-2m^-1

3×10^9×2s^-1

6×10^9s^-1
