The power of a lens is given by the equation [latex]\text{P}=\frac{1}{\text{f}}[/latex]. Sign up and receive the latest tips via email. This formula is applicable for any two lenses, both concave or convex or concave and convex lenses in contact. There can be more than one community in a society. The radii of these spheres are called the radii of curvature of the lens. Lens maker’s formula. It includes every relationship which established among the people. Lens maker s formula and lens formula . This gives, 1 f = (μ1 μ2 − 1) ( 1 R1 − 1 R2) If the ambient medium is taken to be air i.e. Consider a thin convex lens of focal length f and refractive index µ. Using the Lens Maker’s Equation (3) and the appropriate sign for radii R1 and R2, determine the formulae for the focal distance of the hemisphere and the sphere in terms of R and n. Once you have these equations, you should be able to find n from the The complete derivation of lens maker formula is described below. convex lens: A lens having at least one convex surface, such that light passing through it, may be brought to a focus. 1.Let R 1 and R 2 be the radii of curvature of two spherical surfaces ACB and ADB respectively and P be the … Occupation, Business & Technology Education, Equation of Motion with Uniform Acceleration and Relative Velocity, Principle of Conversation of Linear Motion, Verification of the laws of limiting Friction and Angle of Friction, Work-Energy Theorem, Principle of Conservation of Energy and Types of Forces, Motion of a body in a Vertical and Horizontal Circle, Co-planar Force, Moment of a Force, Clockwise and Anticlockwise Moments and Torque, Moment of Inertia and Theorem of Parallel and Perpendicular Axes, Calculation of Moment of Inertia of Rigid Bodies, Angular Momentum and Principle of Conservation of Angular Momentum, Work done by Couple, Kinetic Energy of Rotating and Rolling Body and Acceleration of Rolling Body on an Inclined Plane, Interatomic and Inter molecular Forces and Elastic behaviour of Solid, Energy stored in a Stretched Wire, Poisson's Ratio and Elastic after Effect, Simple Harmonic Motion in Terms of Uniform Circular Motion, Simple Pendulum and Oscillation of a Loaded Spring, Energy in SHM types of Oscillation and Vibration, Pressure, Pascal's Law of Pressure and Upthrust, Archimedes’ Principle, Principle of Flotation and Equilibrium of Floating bodies, Types of Intermolecular Force of Attraction and Molecular Theory of Surface Tension, Some Examples Explaining Surface Tension and Surface Energy, Excess Pressure on Curved Surface of a Liquid and inside Liquid Drop and Shape of Liquid Surface Meniscus, Stream-line and Turbulent Flow, Energy of a Liquid and Bernoulli's Theorem, Escape Velocity and Principle of Launching of Satellite, Calibration of Thermometer, Zeroth Law and Construction of Mercury Thermometer, Coefficient of Linear Expansion by Pullinger's Apparatus, Bimetallic Thermostat and Differential Expansion, Determination of Real Expansivity of liquid and Anomalous Expansion of Water, Principle of Calorimetry and Newton’s Law of Cooling, Determination of Latent Heat of Steam by the Method of Mixture, Dalton’s Law of Partial Pressure, Boyle's Law and Charle's Law, Average Kinetic Energy per Mole of the Gases and Root Mean Square Speed, Derivation of Gas Laws from Kinetic Theory of Gases, Variation with Vapour Pressure with Volume, Conduction, Temperature Gradient and Thermal Conductivity, Thermal Conductivity by Searle's Method and Heat Radiation, Heat Radiation and Surface Temperature of the Sun, Internal Energy, First Law of Thermodynamics and Specific Heat Capacities of a Gas, Isochoric, Isobaric, Reversible and Irreversible Process, Efficiency of Carnot Cycle and Reversibility of Carnot's Engine, Lambert’s Cosine Law and Bunsen’s Photometer, Real and Virtual Images and Curved Images, Mirror Formula for Concave and Convex Mirror, Images Formed by Concave and Convex Mirrors and Determination of Focal Length, Laws of Refraction of Light, Relation between Relative Refractive Indices and Lateral Shift, Real and Apparent Depth, Total Internal Reflection and Critical Angle, Lens Maker’s Formula and Combination of Thin Lenses, Power of Lens and Measurement of Focal Length, Angular Dispersion and Deviation without Dispersion, Spherical Aberration in a Lens and Scattering of Light, Charging a Body by Induction Method and Coulomb's Law, Biot's Experiments , Faradays's Ice Pail Experiment and Surface Density of Charge, Action of Points and Van de Graaff Generator, Electric Field Intensity and Electric Flux, Relation between Electric Intensity and Potential Gradient, Action of Electric field on a Charged Particle and Equipotential, Energy Stored in a Charged Capacitor, Energy Density and Loss of Energy due to Joining of Capacitor, Sharing of Charges between two Capacitors and Dielectric, Dielectrics and Molecular Theory of Induced Charges.
