Question

1.Difference between virtual and real image
2. Application of diffused reflection

Answer 1

A virtual image is formed when light rays originating from a point on oneside of a lens (i.e. the object) are refracted by the lens so that they diverge (move apart from each other) on the other side of the lens. ... But there are no actual light rays that come together at the virtual image location.

Applications of Specular and Diffuse Reflection. ... The glare is the result of the specular reflection of the beam of light from an oncoming car. Normally a roadway would cause diffuse reflection due to its rough surface. But if the surface is wet, water can fill in the crevices and smooth out the surface.
