# Prove that, to three-digit accuracy, h = 4.14 × 10 − 15   eV ⋅ s , as stated in the text.

To determine

To show:

The three-digit accuracy, h=4.14×1015 eVs.

Explanation

Given info:

â€ƒâ€ƒc=3.00Ã—108Â ms

â€ƒâ€ƒh=6.63Ã—10âˆ’34Â Jâ‹…s

Calculation:

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

â€ƒâ€ƒ1J=11.6Ã—10âˆ’19Â eV

Energy of photon in term of frequency and Planck's constant, we get

â€ƒâ€ƒE=hfÂ Â

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

â€ƒâ€ƒhfâ‰ˆ(6.63Ã—10âˆ’34Â J
