jakey said:T=2pi/w or 1x10^-3. unfortunately, it s not in the choices. can someone help? thanks!
Angular frequency, also known as angular speed, is a measure of how quickly an object rotates around a fixed point. It is represented by the symbol ω (omega) and is measured in radians per second.
Angular frequency is inversely proportional to the period of an oscillation. This means that as the angular frequency increases, the period decreases and vice versa.
Angular frequency is a measure of how quickly an object rotates, while phase velocity is a measure of how quickly a wave propagates through a medium. They are related, but they represent different physical phenomena.
Angular frequency and phase velocity are related by the wavelength of a wave. The phase velocity is equal to the angular frequency multiplied by the wavelength.
The formula for calculating angular frequency is ω = 2πf, where f represents the frequency of the oscillation. In other words, the angular frequency is equal to 2π times the frequency.
