Question

6. A photon of light has a wavelength of about 600 nm (1nm = 1 x 10-9 m). What is the energy of this photon of light? Show all calculations leading to an answer.

Answer 1

\[E = \frac{ hc }{ \lambda }\]
\[h = Plank's~constant=6.626 \times 10^{-34}~J-s\]
\[c=speed~of~light = 3.0 \times 10^8~m/s\]
\[\lambda=wavelength~[meters]\]

Answer 2

First of all.. "photon of light" (funny thing..)
Next.. Upvote for @peachpi .. u are right..
