# Do the unit conversions necessary to show that h c = 1240   eV ⋅ nm , as stated in the text.

To determine

The unit conversions necessary to show that, hc=1240 eVnm .

Explanation

Given info:

â€ƒâ€ƒcâ€‰=â€‰2.99792Ã—108ms

â€ƒâ€ƒh=6.62607Ã—10âˆ’34Â Jâ‹…s

Calculation:

Substituting the given values of joule in term of electron volt and meter in term of Nano meter, we get

â€ƒâ€ƒ1â€‰J=11.6Ã—10âˆ’19Â eV

â€ƒâ€ƒ1â€‰m=1.0Ã—109nm

Substituting the values of velocity of light and Planck's constant, we get

â€ƒâ€ƒhcâ‰ˆ(6.62607Ã—10âˆ’34Â J
