A second's pendulum is one who has a time period of:
Correct answer: B. 2s
- A. 1s
- B. 2s
- C. 1/2 s
- D. 0.2 s
Explanation
A. 1s: If a pendulum has a time period of 1 second, it would be referred to as a "one-second pendulum." This means that the pendulum completes one full swing, back and forth, in a time period of 1 second. B. 2s: If a pendulum has a time period of 2 seconds, it would be called a "two-second pendulum." This means that the pendulum takes 2 seconds to complete one full swing, back and forth. C. 1/2s: If a pendulum has a time period of 1/2 second, it would be known as a "half-second pendulum." This means that the pendulum completes one full swing, back and forth, in a time period of half a second. D. 0.2s: If a pendulum has a time period of 0.2 seconds, it would be referred to as a "0.2-second pendulum." This means that the pendulum takes 0.2 seconds to complete one full swing, back and forth.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
