Answer:
(4)
Step-by-step explanation:
L'intersezione si occupa di elementi comuni
segno per intersezione = ∩
A = (1,2,3,4,5)
B = (3,4,5,6,7)
C = (2,4,6,8)
(A∩B)∩C
(A∩B) = (3, 4, 5)
(A∩B)∩C = (4)

<u>Planck relation</u>
where:
- E = Energy of the photon (J).
- h = Planck's constant (J · s).
- f = frequency of light produced (Hz).
Given values:
- E = 3.4 × 10⁻¹⁹ J
- h = 6.626 × 10⁻³⁴ J · s
Substitute the given values into the formula and solve for f:
