What is the geomatrical shape of wavefront emitted from a source in the form of narrow slit ?
When does a convex lens behave as a concave lens ?
When does a convex lens behave as a concave lens ?
What type of motion particles of a medium execute when a wave passes through the medium?
What is the shape of wavefront from distant source of light?
If the object is placed at A and the image is formed at B when the rays are refracted through a convex lens. The position. Of A and B are changeable. Such pair of is called.
Draw the shape of wavefront when a plane wavefront in incident on (i) concave mirror and (ii) prism.
Copy and complete the diagram below to show what happens to the rays of light when they pass through the concave lens.
