a periodic wave travels outward from a source. the waves frequency can be changed. the speed that the wave moves forward does not change. if the waves frequency is decreased, what will happen to its wavelength? choose 1 answer: a wavelength will decrease b wavelength will increase c wavelength will stay the same

Answer

Explanation:

Step1: Recordar la relación entre velocidad, frecuencia y longitud de onda

La velocidad de una onda ($v$), su frecuencia ($f$) y su longitud de onda ($\lambda$) están relacionados por la fórmula $v = f\lambda$.

Step2: Analizar el caso de velocidad constante

Dado que $v$ es constante ($v = f\lambda$), entonces $\lambda=\frac{v}{f}$. Si $f$ disminuye y $v$ es constante, el valor de $\frac{v}{f}$ aumenta. Entonces, la longitud de onda aumenta.

Answer:

B. wavelength will increase
