Question

A 60-vibration-per-second wave travels 30 meters in 1 second. Its frequency is

A. 30 hertz and it travels at 60 m/s
B. 60 hertz and it travels at 30 m/s
C. 1800 hertz and it travels at 2 m/s
D. none of the above

Answer 1

The wave with 60 vibrations per second (or 60 Hz) travels at a speed of 30 m/s, making option B the correct answer.

Step-by-step explanation:

The question pertains to the properties of a wave, specifically its frequency and speed of propagation. In the given scenario, a wave is said to have 60 vibrations per second, which is its frequency. Therefore, the frequency is 60 hertz (Hz). The wave is also described as traveling 30 meters in 1 second. Since speed is defined as distance traveled over time, the speed of the wave is 30 meters per second (m/s).

Consequently, the correct answer is B. 60 hertz and it travels at 30 m/s.
