Frequency is a part of our common, everyday language. For example, it is not uncommon to hear a question like "How frequently do you mow the lawn during the summer months?

If a coil of slinky makes 2 vibrational cycles in one second, then the frequency is 2 Hz. If a coil of slinky makes 3 vibrational cycles in one second, then the frequency is 3 Hz. The quantity frequency is often confused with the quantity period. Period refers to the time that it takes to do something. When an event occurs repeatedly, then we say that the event is periodic and refer to the time for the event to repeat itself as the period. The period of a wave is the time for a particle on a medium to make one complete vibrational cycle.

Period, being a time, is measured in units of time such as seconds, hours, days or years. The period of orbit for the Earth around the Sun is approximately days; it takes days for the Earth to complete a cycle.

The period of a typical class at a high school might be 55 minutes; every 55 minutes a class cycle begins 50 minutes for class and 5 minutes for passing time means that a class begins every 55 minutes. The period for the minute hand on a clock is seconds 60 minutes ; it takes the minute hand seconds to complete one cycle around the clock. Frequency and period are distinctly different, yet related, quantities. User Reviews. User Ratings. External Reviews.

Joynoise publicly announced his departure and have been reflecting on their place and power in the scene ever since. Koch and Kaiser have spent the past months having conversations with themselves and the women in their lives in an attempt to dismantle the structural sexism that has been ingrained in them.

I think that every man needs to look at themselves and really assess the sexism that they were taught. Moving forward, both Kaiser and Koch want to see a completely new, more equal scene rise from the ashes. Loza is hopeful that this reckoning will serve as an important lesson to younger generations who have watched it unfold on social media, fostering a hyper-aware environment where people are encouraged to speak up and hold each other accountable.
