Question

What is an example of divergence of light?
A.Light from streetlights.
B.Light through clouds.
C.Light through denser medium.
D.Light through a prism.

Answer 1

Hint: We know that when a divergent beam of light is incident on a plane mirror then the type formed is Inverted and virtual. So, as we know that plane mirrors are the only type of mirror for which a real object always produces an image that is virtual, erect and of the same size as the object.

Complete answer:
As we know that the plane mirror is a smooth polished surface that can turn the rays of light into the same medium. Also, note that when a divergent beam of light is incident on a plane mirror, it is reflected back as a divergent beam. Also, when the rays of light starting from a point travel in different directions, then the collection of such rays is termed as a divergent beam of light. As mentioned in the solution, the image formed in this case is inverted and virtual. Lens are the things, which will allow the light to pass through them with convergence or divergence. Depending on whether the lens will converge or diverge the rays they are divided into convex and concave lenses. Their capacity for convergence or divergence is given by the power of the lens.
The concave mirror can be analogous to convex lenses. All the properties of the image formed by the concave mirror will be possessed by the image formed due to the convex lens. The only difference between the two images will be the side where images are formed. If images are formed on the object side in a concave mirror, then images will be formed on the other side of the convex lens. Street lights are covered by diverging reflecting surfaces to cover maximum area with light.

Therefore, the correct answer is option A.

Note:
Remember that when an object is placed in front of the lens the rays from the object pass through the lens and suffer refraction and an image is formed. The position where the image forms and the nature of the image formed depends upon the type of lens we use. Various positions of placing an object in front of a convex lens give us various positions of images
