1. Fill a sink or bath tub with water.
2. Practice tapping the cork on the surface of the water (about 3 _times per second works well) to create evenly spaced waves.
3. Tapping the water at the same frequency, move your object in a straight line in one direction in a broad, sweeping motion-not too fast, or you will have a hard _me seeing the effects!
4. As you move the object, try to observe the spacing of the waves extending in front of the object compared to the ones behind it.
5. Try a number of different speeds and tapping frequencies until you can see a spacing difference between the front and back waves.
Stress is measured by the deforming force per unit normal area. Stresses set up in an object due to of the action of forces can be divided into three broad categories (a) Ten

actually in my college we are going to celebrate department function for physics we have to keep demos in physics for a project but i don''t have any idea will u help me
Lenz's law (H.F. Lenz; 1835): An induced electric current always pass in such direction that it opposes the change generating it.
Ampere; A (after A.M. Ampere, 1775-1836) The basic SI unit of electric current, described as the current that, while going through two infinitely-long parallel conductors of ne
Defects of Vision Long Sightened When a person can see far objects clearly but cannot see near object clearly then this defect of vision is called as long sightedness.
