Wave Phenomenon

Question

When we were talking about variations in waves in the same medium, the _________________ is a constant. Therefore, _______________ varies inversely with ________________.

When we are talking about a wave crossing into a different medium, the _________________ is a constant. Therefore, _______________ varies directly with __________________.

Answer 1

Same medium: v is constant, λ and f are inverse.

At a boundary between media: f is constant, λ and v are directly proportional. (Think about colors through a window)

For standing waves, λ is set (there are multiple discrete values), f and v are proportional. (If you tighten a guitar string, you increase the velocity which increases the frequency (pitch)).

Take care.
