So I have always studied that a wave speed only depends on the medium. And sure, I can memorize that any day.
But in practice, I just don't understand how this is possible. The equation for velocity is wavelength*frequency.
Here's an example:
665. Compared to a 440 Hz sound wave, a 880 Hz sound wave will travel
A. half as fast
B. the same speed
C. twice as fast
D. four times as fast
Answer: B
Okay, so my flashcard would agree. But how is this really possible? If frequency increases, then according to the velocity equation above, so should velocity. So what's going on here?
