(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A quantum of electromagnetic radiation has

an energy of 0.877 keV.

What is its wavelength? The speed of light

is 2.99792 × 10

8 m/s, and Planck’s constant

is 6.62607 × 10−34J · s.

Answer in units of nm

2. Relevant equations

E=hf

v=fλ

... λ=v/(E/h)

3. The attempt at a solution

When i solved, i got 1.413728e-9 nm... I have checked my units. can some just help and point me in the right direction
