Materials Required: A Resistance wire, voltmeter, ammeter, battery, rheostat, meter scale, one way key, connecting wires etc.

Theory: If I be the current flowing through a conductor & V be the potential difference across its ends, then according to Ohm s law
V I
or V = RI
Where, R is the constant of proportionality. It is known as resistance of the conductor.
V/I=R
R depends upon the nature of material, temperature & dimensions of the conductor.

Procedure:
1. Clean the ends of the connecting wires with the help of sand p ....etc

AIM:
To investigate the dependence of the angle of deviation, on the angle of incidence, using a hollow prism filled, one by one, with different transparent fluids.

APPARATUS REQUIRED:
A hollow glass prism;
Drawing board;
White sheets;
Drawing pins;
Pins;
A sharp pencil;
Glycerine; &
Water.

RESULT:
The graphs for both the liquids are similar.
(For water) = ..
(For glycerine) = ..
The minimum deviation
for glycerine is greater than that for water. ....etc

A sound level meter is a hollow wodden box used in the laboratory to study the transverse vibrations of the string. It is also called monochord because it often has only one sequence. In the rectangular box of wood there are two fixed bridges, near the ends, and at one end there is a pulley. A rope, often a steel wire is attached at one end over the bridges and pulley, and attached to a weight support that hangs below the pulley. Weights may be added to the support to cause tension in the wire, and a third movable bridge may be placed below it ....etc

Sonometer:

A sonometer is a device based on the principle of Resonance. It is used to verify the laws of vibration of stretched string and also to determine the frequency of a tuning fork.

Resonance: When the frequency of the applied force is equal to the natural frequency of the body, the body vibrates with very large amplitude. Corresponding intensity of sound will be maximum. This phenomenon is known as resonance.

A sonometer consists of a rectangular hollow wooden box called resonance box. resonance box

Our Objective:

To determine the frequency of alternating current using a sonometer.

The Theory:

A sonometer is an apparatus used to study the transverse vibrations of stretched strings. It is in the form of a hollow wooden rectangular box. On the wooden rectangular box there are two bridges and a pulley at one end. A wire string is attached to one end of the wooden box, run over the bridges and pulley and carries a weight hanger at the free end

A sonometer is used to determine the frequency of alternating current. A step down transformer ....etc

Q.1: What is meant by electric current?
Ans. The flow of electrons.

Q.2: What are A.C. and D.C. currents?
Ans. Alternating current (A.C.) changes its direction with a definite frequency. The direct current (D.C.) flows in one direction only.

Q.3: What is meant by frequency?
Ans. Number of vibrations per sec.

Q.4: What is the frequency of A.C. in Nepal?
Ans. 50 cycles/s.

Q.5: What types of waves are produced in the thread?
Ans. Transverse stationary waves.

Q.6: What kind of vibrations are produced in the thread?
Ans. Forced ....etc
