What is the energy of light with a wavelength of 589 nm? (The speed of light in a vacuum is 3.00 x 10^8 m/s, and Planck's constant is 6.626 x 10^-34 Jos.) A. 3.37 x 10^-19 J
B. 3.37 x 10^-28 J
C. 2.96 % 10^18 J
D. 2.96 % 10^27 J

B

Explanation:

= 3.37 x 10^-28 J

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

what is the question here. i think you messed up.
