Spherometer – Measure the radius of curvature of a spherical surface | Labkafe
Aim: To determine the radius of curvature of a given spherical surface by a Spherometer. Apparatus: Theory: A spherometer is a measuring instrument used to measure the radius of curvature of a spherical surface and a very small thickness. Figure 3.1 is a schematic diagram of a single disk spherometer. It consists of a central…

How to use Vernier Caliper to find out least count and measure diameter of Spherical body and Beaker | Labkafe
Aim:To measure (a) diameter of a small spherical/cylindrical body and (b) to measure internal diameter and depth of a given beaker/calorimeter using Vernier Callipers and (c) hence find its volume Apparatus: Theory: A Vernier Calliper has two scales–one main scale and a Vernier scale. Vernier Scale slides along the main scale. The main scale and…

Simple Pendulum Experiment Class 11 | Labkafe
Aim: Using a simple pendulum, plot its L-T2 graph and use it to find the effective length of second’s pendulum. Apparatus: Theory: A simple pendulum consists of a heavy metallic (brass) sphere with a hook (bob) suspended from a rigid stand, with clamp by a weightless inextensible and perfectly flexible thread through a slit cork, capable…

Beam Balance: Physics Experiment Class 11 to determine mass of two different objects | Physical Balance
Aim: To determine the mass of two different objects using a beam balance. Apparatus: Theory : A physical balance or Beam Balance is a weighing instrument that helps in measuring the weight (or gravitational mass) of an object by making use of the principle of moments. It consists of a metal beam B with a…

Screw Gauge experiment class 11 PDF | Micrometer | Least Count | Labkafe
Aim: To measure (a) diameter of a given wire (b) thickness of a given sheet and (c) volume of an irregular lamina using screw gauge. Apparatus: Theory: Using Vernier Callipers we can measure length accurately up to 0.1 mm. To measure more accurately, up to 0.01 mm or 0.005 mm, we use screw gauge. A…

Simple Pendulum Experiment Physics Practical Class 11 and 9 | Labkafe
Pendulum Experiment Physics Practical Aim: To study variation of time period of a simple pendulum experiment physics practical of a given length by taking bobs of same size but different masses and interpret the result. Apparatus: Theory: See Experiment 6. The time period (T) of a simple pendulum for oscillations of small amplitude, is given…
