Aphoton has 3.4 × 10–18 joules of energy. planck’s constant is 6.63 × 10–34 j•s. what is the frequency of the photon? 5.12 × 10–15 hz 1.95 × 1016 hz 5.12 × 1015 hz 1.95 × 10–16 hz

For this problem, you can use the equation that represents the relationship between energy, frequency, and Planck’s constant. This formula is:

E=hu

where E is energy, u is frequency, and h is planck’s constant. Plugging in your numbers and solving for u:

(3.4x10^-18)=(6.626x10^-34)(u)
u=5.13x10^15 hertz, or the third option.

C. 5.12 x 10^15

Explanation:

Walt Whitman was agreat poet and was born on 1819
  The lines from Walt Whitman's “I Hear America Singing” that  describes a unified America are
I hear America singing, the varied carols I hear
The option A is correct because the poet is talking about varied that means more than one or diverse so in these lines he describe the America as unified nation
