Davisson and Germer scattered electrons from a crystal of nickel.
The scattered electrons formed a strong diffraction pattern.
What significant conclusion was drawn from this experiment?
Ans- Electrons acted like waves
A single fixed pulley Set up a one fixed pulley as shown in the diagram below. By means of weights see how much force is needed to lift weights of 25, 50, 75, 100 and 200 g. Ca
Q. A transistor is connected in CE configuration. The voltage drop across the load resistance ( Rc) 3 k is 6 V. Find the base current. The current gain α of the transistor is 0.97.

For the double-beam oscilloscope displays shown in Figure, determine (a) their frequency (b) their r.m.s. values (c) their phase difference. The 'time/cm' switch is on 10
Vertical Circular Motion A mass is in circular motion within the vertical plane. We show the weight and force exerted through the tension within the string.
Explain the terms 'Magnetic Dip' and 'Magnetic Declination' with the help of relevant diagrams.
