# Calculate the Energy of Light Using Wavelength

CHEM-SI2PYB

The hydrogen atom produces a line spectrum that produces only 4 lines in the visible spectrum. One of those lines occurs at a wavelength of 410.1 nm.

Calculate the energy of a photon of violet light emitted with that wavelength.

$h=6.626\times { 10 }^{ -34 }\text{ } J\cdot s\\\ c=3.00\times { 10 }^{ 8 }\text{ } \cfrac { m }{ s }$

A

$2.06\times { 10 }^{ -19\text{ } }J$

B

$4.85\times { 10 }^{ -19\\\text{ } }J$

C

$5.27\times { 10 }^{ -19\text{ } }J$

D

$8.13\times { 10 }^{ -19\text{ } }J$

E

$1.23\times { 10 }^{ -19}\text{ }J$
