Brilliant All Formula Of Ray Optics
Let μ1 μ and μ2 1 and let for i ic r 90º then.
All formula of ray optics. Relation between Refractive indices According to Snells law By Snells law 4. Ic is called the critical angle. Helps in quick revision for CBSE NEET JEE Mains and JEE Advanced.
The power of a lens P is its ability to deviate the ray towards axis. If the focal length is given in meters m the power of the lens if measured in Diopters D as in the unit of power of the lens is diopter. B The angle of incidence is equal to the angle of reflection.
Physics formulas from Mechanics Waves and Oscillations Optics Heat and Thermodynamics Electricity and Magnetism and Modern Physics. Light from a lamp travels in all directions which is a divergent beam. Lens makers formula 1f μ - 1 1R 1 - 1R 2 Where μ is the refractive index of material of the lens R 1 and R 2 are the radii of curvature of the two surfaces of the lens.
A search light emits a parallel beam of light Figa. So i r. In general the light will enter the interface between the two media at an angle.
The power of the lens is the inverse of focal length. Focal Length of Thin Lenses. These list of formula booklet physics of class 12 chapter Ray Optics is useful and highly.
Physics Formulas OpticsCheat sheet. Brewsters Law Lens Formula Youngs Double Silt Experiment. Snells Law describes how a light ray behaves when it passes from a medium with index of refraction n 1 to a medium with a different index of refraction n 2.
