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.
Calculate the density of silver which crystallizes in the face-centred cubic structure. The distance between the nearest silver atoms in this structure is 287 pm. (Molar mass of
Determine the Einstein relations by upward and downward transition. While the system is in equilibrium, the upward and downward transition rates should be equal. N 1 ρ(ν) B
Defect of short sightedness In this defect the image of the object is formed in front of retina or the lens become so converging.
What is SI unit of force
An element exists in two solid phases (labelled P1 and P2). The standard molar entropies of P1 and P2 are 21.9 J mol -1 K -1 and 23.3 J mol -1 K -1 respectively. The
