Amazing Ray Optics Formula Sheet
Ray Optics and Optical Instruments 311 this case is to be taken as normal to the tangent to surface at the point of incidence.
Ray optics formula sheet. Total Internal Reflection and Critical angle Total internal reflection occurs when light is passing through a medium call it 1 like glass or plastic with an. Hence any interference pattern formed on the screen would last only for 10 9 sec. 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.
The incident ray the refracted ray and normal lie on the same plane. Ray Optics and Optical Instruments Notes Revision Summary Important Formulae Subscribe For Latest Updates. Critical angle ic.
Laws of Reflection of light. Laws of Reflection First law of reflection states that. V 1 velocity of light in first medium.
A billionth of a second and then the pattern will. Important formulae basic concepts Chapter. Even if all the atoms were emitting light pulses under similar conditions waves from different atoms would differ in their initial phases.
Consequently light coming out from the holes S 1 and S 2 will have a fixed phase relationship only for 10 9 sec. Physics Formulas for Class 11 and Class 12 Author. In general the light will enter the interface between the two media at an angle.
Ic is called the critical angle. Real depth and Apparent depth 6. That is the normal is along the radius the line joining the.
