The formula to calculate will be:
![(E)/(h) * n * v~\bf~where:](https://img.qammunity.org/2019/formulas/biology/middle-school/bbjrb1kujcnfkciyht7a2ue9uzymvr8fk5.png)
E = energy (11000 J)
H = Planck's constant (6.62607004 × 10-34 m2)
N = number of photons
V = frequency (880)
Solution:
} * n * 880 [/tex]
![7.288677 * 10^(-30) * n * 880](https://img.qammunity.org/2019/formulas/biology/middle-school/2z6clqe8yti9phsaryvi4aiitjej3m5lo0.png)
And that is the final step to calculating the answer.
Hope it helped,
