Solution

Para calcular el ángulo de refracción, necesitamos aplicar la Ley de Snell, que se expresa como:

n1sin(θ1)=n2sin(θ2) n_1 \sin(\theta_1) = n_2 \sin(\theta_2)

donde:

  • n1 n_1 es el índice de refracción del primer medio,
  • θ1 \theta_1 es el ángulo de incidencia,
  • n2 n_2 es el índice de refracción del segundo medio,
  • θ2 \theta_2 es el ángulo de refracción.

Dado que la pregunta no proporciona explícitamente los índices de refracción ni los ángulos de incidencia y refracción, asumiremos que los números dados (40.574, 644.6) están relacionados con estos valores. Sin embargo, la información no es clara. Vamos a suponer que:

  • 40.574 es el ángulo de incidencia (θ1 \theta_1 ),
  • 644.6 es el índice de refracción del segundo medio (n2 n_2 ),
  • 15 es el índice de refracción del primer medio (n1 n_1 ).

Siguiendo estos supuestos, podemos reorganizar la Ley de Snell para resolver el ángulo de refracción (θ2 \theta_2 ):

sin(θ2)=n1sin(θ1)n2 \sin(\theta_2) = \frac{n_1 \sin(\theta_1)}{n_2}

Primero, convertimos el ángulo de incidencia a radianes si está en grados:

θ1=40.574 \theta_1 = 40.574^\circ

θ1 (en radianes)=40.574×π1800.708 radianes \theta_1 \text{ (en radianes)} = 40.574 \times \frac{\pi}{180} \approx 0.708 \text{ radianes}

Ahora, aplicamos la Ley de Snell:

sin(θ2)=15sin(0.708)644.6 \sin(\theta_2) = \frac{15 \sin(0.708)}{644.6}

Calculamos sin(0.708) \sin(0.708) :

sin(0.708)0.651 \sin(0.708) \approx 0.651

Entonces:

sin(θ2)=15×0.651644.69.765644.60.015 \sin(\theta_2) = \frac{15 \times 0.651}{644.6} \approx \frac{9.765}{644.6} \approx 0.015

Finalmente, encontramos θ2 \theta_2 tomando el arco seno (inverso del seno):

θ2=arcsin(0.015)0.86 \theta_2 = \arcsin(0.015) \approx 0.86^\circ

Por lo tanto, el ángulo de refracción es aproximadamente 0.86 0.86^\circ .
