CBSE Class 12-science Physics Huygen's Principle
- huygens wave theory ?
- wave lets means
- when ray of light passes from one medium to another medium
- Define Huygens Principle
- An object is placed at 10 cm distance infront of a concave mirror of radius of curvature of 20 cm. Find the position,nature and magnification of the image.

Hi
- define wave front.state
- use wave theory to verify the laws of reflection and law of reflection
- state and explain huygens principle explain how a reflected wavefront is constructed when light travels from denser medium to rarer medium
- (a) In young’s double slit experiment, deduce the conditions for obtaining constructive and destructive interference fringes. Hence, deduce the expression for the fringe width. (b) Show that the fringe pattern on the screen is actually a superposition of slit diffraction from each slit. (c) What should be the width of each slit to obtain 10 maxima of the double slit pattern within the central maximum of the single slit pattern, for green light of wavelength 500 nm, if the separation between two slits is 1 mm?
