Is frequency the number of times an object vibrates per second?

Question

True or False?

Answer 1

Frequency is the rate of oscillation per unit time. That unit of time can be seconds or hours or days or any unit of time you want. The common unit of frequency is Hertz, abbreviated Hz, which stands for cycles per second. Kilohertz (kHz) is 1000 cycles per second, and Megahertz (Mhz) is 1 million cycles per second.

So, the number of times an object vibrates per second is indeed a frequency.

Answer 2

true. Frequency(Hz) = waves/time(s)
