The formula to calculate will be:
[tex] \frac{E}{h} * n * v~\bf~where: [/tex]
E = energy (11000 J)
H = Planck's constant (6.62607004 × 10-34 m2)
N = number of photons
V = frequency (880)
Solution:
[tex] \frac{11000}{6.62607004 * [tex] 10^{-34} [/tex]} * n * 880 [/tex]
[tex] 7.288677 * 10^{-30} * n * 880 [/tex]
And that is the final step to calculating the answer.
Hope it helped,
