Longitud de onda (ALM183S)

La distan

cia entre dos puntos de igual amplitud de ondas sucesivas de una señal periódica, nos da la longitud de onda. Esta distancia puede ser medida entre dos puntos de máximo, de mínimo o aún en que el desfase sea de 360 ??grados, como muestra la figura 1.


 

 

 

 

Para ondas electromagnéticas y ondas sonoras la longitud de onda se mide en metros y sus múltiples / submúltiplos. Sin embargo, para ondas muy cortas es común usar el Angstrom (?) como unidad de medida.

La longitud de onda y la frecuencia se relacionan por la siguiente fórmula:

 

V = λ x ff

 

Donde:

V es la velocidad de propagación de la señal considerada

λ es la longitud de onda en metros

f es la frecuencia de la señal en hertz.

En cuanto a la frecuencia, menor será la longitud de onda, y que para las frecuencias muy altas, las longitudes de onda pueden ser muy pequeñas. Vea también el tema del espectro para saber más.
