Wave fronts & interference

The radius of the front and rear wheels of a carriage are a and b, and c is the distance between the front an drear axles. A particle of dust driven from the highest point of the rear wheel is observed to alight on the highest point of the front wheel. Find the velocity of the carriage.

A plane wave front falls on a convex lens. The emergent wave front is

Nature of wave front depends on

Air Masses And Fronts

Draw a diagram to show refraction of a plane wave front incident in a convex lens and hence draw the refracted wave front

An object is placed at a large distance in front of a concave mirror of radius of curvature 40 cm. The image will be formed in front of the mirror at a distance of :

a) Define a wave front. b) Draw the diagram to show the shape of plane wave front as they pass through (i) a thin prism and (ii) a thin convex lens. State the nature of refracted wave front. c) Verify Snell’s law of refraction using Huygens’s principle
