Reflection of Light


Description: Reflection of light occurs when light rays bounce off a surface, obeying the law of reflection, maintaining angle of incidence


The Mirror Equation


Description: The mirror equation relates the object distance, image distance, and focal length of a mirror in optics: 1/f = 1/o + 1/i.


Critical Angle and TIR


Description: Critical angle: angle at which light bends from one medium to another, refracts along the interface, or reflects internally.


Lens


Description: A lens refracts light to focus an image, crucial in cameras and glasses, bending light to converge or diverge.


Lens and Prism Formula


Description: Lens formula: 1/f = 1/u + 1/v, where f is focal length, u is object distance, v is image distance. Prism bends light.


Dispersion and Deviation in Prism


Description: Splitting light into its component colors due to wavelength dependence. Deviation: Light bending when passing through a prism.


Optical Instrument


Description: Optical instruments in optics include microscopes, telescopes, spectrometers, designed to manipulate or measure light for various purposes.


Study of Different Telescopes


Description: Different types of telescopes include refracting telescopes, reflecting telescopes, radio telescopes, X-ray telescopes, and space telescopes like the Hubble.
