Exercício Unicamp 2027 simulado - Algumas técnicas de impressão tridimensional utilizam luz

Text for questions 61, 62, and 63. Advanced 3D manufacturing equipment is capable of producing miniatures of various colossal historical monuments, measuring just over 100 μm. Details of the pieces are only revealed under an electron microscope. QUESTION 63 Some three-dimensional printing techniques use ultraviolet (UV) light to sensitize the resin in layers, thus producing a 3D piece. In atmospheric air, where the speed of light is v ≈ 3.0 × 10⁸ m/s, the wavelength of UV light most commonly used for this process is λ = 400 nm, whose frequency is: a) 7.5 × 10¹⁴ Hz. b) 1.2 × 10² Hz. c) 4.0 × 10⁻⁷ Hz. d) 1.3 × 10⁻¹⁵ Hz.
