Contents:

Unit 1: Vernier Callipers: Measuring Length and Diameter of a Small Cylinder

Experiment 1: To determine the least count of the vernier callipers and measure the length and diameter of a small cylinder, may be a metal rod of length 2 to 3 cm and diameter 1 to 2 cm

Unit 2: Screw Gauge: Measuring Diameter of a Wire

Experiment 2: To determine the pitch and least count of the given screw gauge and measure the mean radius of a given wire

Unit 3: Calculation of Volume, Mass and Density of a Regular Solid Body

Experiment 3: To measure the length, breadth and thickness of a glass block using a metre rule and calculate its volume in cm3 and m3. Then to determine the mass of the block in g and kg using a physical balance and to calculate the density of glass in cgs and SI units using mass and volume in respective units. Obtain the relation between the cgs and SI units of density.

Unit 4: Measurement of Volume of a Metal Bob (Pendulum Bob)

Experiment 4: To measure the volume of a metal bob (pendulum bob) from the readings of water level in a measuring cylinder using displacement method and to verify the same volume from the radius measured using vernier callipers

Unit 5: Calculation of Time Period of a Simple Pendulum

Experiment 5: To calculate the time periods (T) and their squares (T2) for each length (l) for 20 oscillations of a simple pendulum of lengths about 70, 80, 90, 100 and 110 cm each. Plot a graph of l vs T2, also obtain its slope and calculate the value of g in the laboratory by the method, g = 4p2 × slope.

Unit 6: Relationship Between Celsius and Fahrenheit Scales of Temperature

Experiment 6: To determine the temperature of water ranging from ice cold water to hot water using thermometers having Celsius and Fahrenheit scales, and obtain the relationship between the two scales of temperature and plot a graph of TF vs TC

Unit 7: Reflection of Light through a Plane Mirror

Experiment 7.1: To verify the laws of reflection of light by using a plane mirror

Experiment 7.2: To prove that the image formed in a plane mirror is as far behind the mirror as the object is in front of it

Unit 8: Reflection of Light through Spherical Mirrors

Experiment 8.1: To obtain the focal length of a concave mirror by distant object method

Experiment 8.2: To obtain the focal length of a concave mirror by one needle method

Unit 9: Current Electricity

Experiment 9: To observe the brightness of two bulbs connected in (i) series and (ii) parallel, and to find the resultant resistant of the two bulb

Unit 10: Magnetism

Experiment 10: To plot the magnetic field lines around a bar magnet and to find the regions where the combined magnetic field of the magnet and the earth (resultant magnetic field) is (i) strongest, (ii) very weak but not zero and (iii) zero

Unit 11: Archimedes’ Principle

Experiment 11: To determine the weight of a metal ball in air as well as in water using a spring balance and to verify the Archimedes’ principle
