Hi. Its Mr. Andersen. And this is AP Physics essentials video 104. It is on wave period and frequency. Period is the time between oscillations in a wave. And frequency is going to be how many oscillations or waves do we have per unit time. Now it is sometimes easy to confuse frequency with the velocity of the wave. So we are not even going to start with waves. We are just going to start with some flashing lights. And so the light on the left is flashing. Try to figure out the period. How much time is there between each flash? And the right answer is there is 1 second. And so the period or the capital T is 1 second. There is a flash every one second. That is the period. What is the frequency then? Well, we are having the flashes, and so it is how many flashes we have per second. And since we have 1 flash every second, our frequency is 1 flash per 1 second. Now the units for that is going to be in hertz. And so our frequency is 1 hertz. Now lets look at the other light. So it is flash
