Shoulder pain is any pain in or around the shoulder joint. When tendons become trapped under the acromion, the rigid bony arch of the shoulder blade, it can cause shoulder pain called impingement syndrome.
The period for a simple pendulum does not depend on the mass or the initial anglular displacement, but depends only on the length L of the string and the value of the gravitational field strength g, according to The mpeg movie at left (39.5 kB) shows two pendula, with different lengths.
Lesson 44: Frequency, Wavelength, & Amplitude. The period means that it will take 4.5 seconds for the pendulum to swing back and forth once. So, I expect that my frequency will be a decimal, since it will complete a fraction of a swing per second. Be careful when changing the 700nm into metres.mplitude is a measure of how big the wave is. 1  Imagine a wave in the ocean. 2  What you are actually seeing are waves with different amplitudes. 3  They might have the exact same frequency and wavelength, but the amplitudes of the waves can be very different.
