Un niño está parado frente a un acantilado, emite un sonido, el cual se refleja. Si en ir y volver el sonido se demoró 0,8 [s] y la rapidez del sonido en el aire es de 340 [m/s], ¿a qué distancia se encuentra el niño del acantilado? El cuarzo tiene un índice de refracción de 1.5. La rapidez de propagación de la luz en su interior es:

Cierto movimiento ondulatorio posee una frecuencia de 10 ciclos/s y una longitud de onda de 3 m. así que su velocidad de propagación es

5. La nota musical “ la ” tiene una frecuencia, por convenio internacional de 440 Hz. Si en el aire se propaga con una velocidad de 340 m/s y en el agua lo hace a 1400 m/s, calcula su longitud de onda en esos medios.​
