Want this question answered?
The time that it "takes" is the period.
Suppose that a pendulum has a period of 1.5 seconds. How long does it take to make a complete back and forth vibration? Is this 1.5 second period pendulum longer or shorter in length than a 1 second period pendulum?
2 Seconds
A pendulum whose period is precisely two seconds, one second for a swing forward and one second for a swing back, has a length of 0.994 m or 39.1 inches.
"Period" has the dimensions of time. Suitable units are the second, the minute, the hour, the fortnight, etc.
Second's pendulum is the one which has 2 second as its Time period.
The time that it "takes" is the period.
The period is 1 second.
Suppose that a pendulum has a period of 1.5 seconds. How long does it take to make a complete back and forth vibration? Is this 1.5 second period pendulum longer or shorter in length than a 1 second period pendulum?

That depends on the period of the clock's pendulum. If we assume it's one second, then it does 1800 cycles in half an hour.
1/4 Hertz or 1.4 per second.
This pendulum has a length of 0.45 meters. On the surface of the moon, its period would be 3.31 seconds where g = 1.62m/s^2
If the length of the second pendulum of the earth is about 1 meter, the length of the second pendulum should be between 0.3 and 0.5 meters.
The answer is cleverly embedded in the question. If it takes one second to make a complete vibration, then that's the period.
