Molve in Action Video

Shock absorbers in automobiles are on fo the practical applications of damping motion. A shock absorber consists of a piston moving through a liquid such as oil as in figure

The continuous decrease of amplitude of oscillator is called damped oscillator and the oscillations are called damped oscillations,

Consider the following example. Two cycles of a wave pass a fixed point every second, and the velocity of the wave train is 4 feet per second. What is the wavelength? The formula for determining wavelength is as follows:

If you know the velocity of a wave, you can determine the wavelength by dividing the velocity by the frequency. As an equation:

Definition: Velocity of propagation is the rate at which the disturbance travels through the medium, or the velocity with which the crest of the wave moves along.

The two types of wave motion, Transverse and Longitudinal, have many of the same characteristics, such as frequency, amplitude, and wavelength.

The Top Success people in the work How to become a successful person. Consider this: You will never be considered weak if you manage your time to achieve maximum results. With the proper approach, you may be come indispensable to your organization and role model to others who admire your effectiveness. Remember that delegates benefit from assisting you. Research has also shown that children who are assigned household chores develop self-confidence as well as imposer of accomplishment from helping you. If you assign task base on an individual strengths and preference they are likely to enjoy the wok and complete it in a timely manner, they are likely to enjoy the work. Change your Habits: All of us develop habits that are suppose to save time, but sometimes we take the behavior too far and it becomes a detriment. Some of us retain habits long after they serve their purpose, blow good habits out of proportion or hold on to time wasting habits. For example, if yo take a few minutes each day to order your desk at the beginning or end of the day, this is a positive behavior and can save you valuable time in a crunch.

Characteristics Of Waves Motion

The two types of wave motion, 
Transverse and Longitudinal, have many of the same characteristics, such as frequency, amplitude, and wavelength

Another important characteristic that these two types of wave motion share is VELOCITY

Definition:

Velocity of propagation is the rate at which the disturbance travels through the medium, or the velocity with which the crest of the wave moves along. The velocity of the wave depends both on the type of wave (light, sound, or radio) and type of medium (air, water, or metal). If longitudinal waves are plotted as a graph, they appear as transverse waves. This fact is illustrated in figure 







The frequency of a longitudinal wave, like that of a transverse wave, is the number of complete cycles the wave makes during a specific unit of time. The higher the frequency, the greater is the number of compression and expansions per unit of time.
In the two types of wave motion described in the preceding discussion, the following quantities are of interest:
  • The PERIOD, which is the time (T) in which one complete vibratory cycle of events occurs,
  • The FREQUENCY OF VIBRATION (f), which is the number of cycles taking place in one second, and
  • The WAVELENGTH, which is the distance the disturbance travels during one period of vibration.
Now, consider the following concept. If a vibrating object makes a certain number of vibrations per second, then 1 second divided by the number of vibrations is equal to the period of time of 1 vibration. In other words, the period, or time, of 1 vibration is the reciprocal of the frequency; thus,
If you know the velocity of a wave, you can determine the wavelength by dividing the velocity by the frequency. As an equation:

When you use the above equation, be careful to express velocity and wavelength in the proper units of length.

For example, in the English system, if the velocity (expressed in feet per second) is divided by the frequency (expressed in cycles per second, or Hz), the wavelength is given in feet per cycle. If the metric system is used and the velocity (expressed in meters per second) is divided by the frequency (expressed in cycles per second), the wavelength is given in meters per cycle. Be sure to express both the wavelength and the frequency in the same units. (Feet per cycle and meters per cycle are normally abbreviated as feet or meters because one wavelength indicates one cycle.) Because this equation holds true for both transverse and longitudinal waves, it is used in the study of both electromagnetic waves and sound waves.
Consider the following example. Two cycles of a wave pass a fixed point every second, and the velocity of the wave train is 4 feet per second. What is the wavelength? The formula for determining wavelength is as follows:






Waves As Carrier Of Energy

Q.8.  Explain waves as carrier of energy and write the two methods of transfer of energy.

Ans: 
      Energy can be transfer from are point to another by two methods

                  i  Through Matter                                    ii   Through waves

Trough Matter:

In the First Case we can take example of a bullet which is fired from a gun. It has kinetic energy which is carried by the bullet and is transferred this energy to the target when it hits the target. Similarly the fast moving water coming out for the tunnel of a dam has K.E which is transferred to the turbine when water strikes its blades.
The other method of transfer of energy is by the help of waves without transfer of mass.

Through Waves.

Energy can be transferred from one place to another place through waves, For example energy is transferred from the sun to Earth by means of waves.

Experiment:

when a stone is dropped into a pond of water, then energy is transferred from stone to the water and as a result waves are produced in the water.
These waves spread over surface of water and molecules of water start oscillating.

If apiece of cork is already placed in water we can easily observe the oscillating motion of the cork. The propagation of waves over surface of water carries energy which is being transferred to molecules of water. It is an example of transfer of energy without transfer of mass.
