Una onda se propaga en un medio 1, con una velocidad de 70m/s y una frecuencia de
20Hz. Luego incide en un Medio 2 con un ángulo de 80° dónde su velocidad de
propagación será de 35 m/s.
a. ¿Cuál es el ángulo de refracción de la onda considerada y la longitud de onda en el
medio 2?
b. Si el ángulo de incidencia es mayor al ángulo refractado se espera que la velocidad
disminuya o aumente al atravesar el obstáculo. ¿A qué atribuyes este fenómeno?
