Image formed by a concave lens is always ________________.[1 Mark](a) real and erect(b) real and inverted(c) virtual and magnified(d) virtual and diminished

To answer the question regarding the type of image formed by a concave lens, let's analyze the options closely.

1. Understanding Concave Lens Properties: A concave lens is a diverging lens, meaning it causes parallel rays of light to spread outwards. The important characteristics of the images formed by a concave lens are that they are always virtual, upright (erect), and diminished (smaller) than the object.

2. Reviewing the Options:

   • (a) real and erect: Concave lenses do not form real images; this option is incorrect.
   • (b) real and inverted: Again, concave lenses do not form real images. This option is also incorrect.
   • (c) virtual and magnified: While concave lenses produce virtual images, they do not magnify them. This option is incorrect.
   • (d) virtual and diminished: This option accurately reflects the characteristics of images formed by concave lenses.

Final Answer

The correct answer is: (d) virtual and diminished.
