Practicing Self-Care. 1  1. Take care of yourself. There are many small steps to this one action. 2  2. Put care into your appearance. You don't have to look like Brad Pitt to start building your self confidence. 3  3. Exercise regularly. Part of taking care of yourself is getting exercise.  4. Sleep well.
Stationary Waves. Stationary or standing waves are formed in a medium when two waves having equal amplitude and frequency moving in opposite directions along the same line, interfere in a confined space. Generally, such waves are formed by the superposition of a forward wave and the reflected wave. Both longitudinal and transverse types of waves can form a stationary wave. When reflection occurs at a free end, there is no reversal of phase. i.e., a crest returns as a crest and a trough as a trough.
The upwards and downwards motion of particles in transverse waves and the horizontal motion of particles in longitudinal waves transfer energy through the medium of propagation. Waves transfer energy without transferring mass. An ocean wave washing up against the shore does not carry individual water particles from deep in the ocean to the shore. The water molecules, salt, sand and other particles excited by the wave vibrate perpendicular to the direction of wave propagation, making these transverse waves. They are lifted up as the crest of the wave passes. If there are several consecutive waves, the crest is succeeded by a trough, which displaces the medium particles downwards.
