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.
Three coils each having resistance 3 Ω and inductive reactance 4Ω are linked (i) instar and (ii) in delta to a 415V, 3-phase supply. Calculate for each connection (a)
Will a DC motor actually produce voltage if it is spun in reverse? It'll make voltage if you spin it forwards, too. The only difference among a DC motor and a DC generator is w
Charging: During charging the device is linked across a source of D.C. supply having a voltage of about 3 volts. When the circuit is switched on the current flows inside the cell

Q When calculate Planck's constant, a student's calculations produce values of 5.78 × 10 -34 J·s and 7.29 × 10 -34 J·s. If the accepted value is 6.63 × 10 -34 J·s, what is
A radiation of 500nm is incident on a metal surface whose work function is 3ev.why do we not observe the phenomenon of photoelectric effect? Ans) Because the energy of radiation i
