Waves, Light and Sound - Physics 101 / AP Physics 1 Review with Dianna Cowern

Lesson 17 (Waves, Light, and Sound) of Dianna's Intro Physics Class on Physics Girl. Never taken physics before? Want to learn the basics of physics? Need a review of AP Physics concepts before the exam? This course is for you! Exercises in this video: 1. You measure an oscillating wave to have a wavelength of .5m and a frequency of .5Hz. What is the speed of the wave in that medium? What would the wavelength of a wave with frequency 2.5Hz be? 2. You tune your car radio to your favorite station, 93.5 on the dial. That’s a frequency of 93.5MHz. What is the wavelength of that radio wave? 3. At sea level, the speed of sound in air is around 343m/s. The speed of light in air is about 3.00x10^8m/s. If you are watching a rocket launch 11km away, what will be the difference between the time you see the launch and the time you hear it?
