# Mark â€˜Tâ€™ if the statement is true and â€˜Fâ€™ if it is false:$(a)$. We can obtain an enlarged and erect image with a convex mirror. $(T/F)$$(b). A concave lens always forms a virtual image. (T/F)$$(c)$. We can obtain a real, enlarged, and inverted image by a concave mirror. $(T/F)$$(d). A real image cannot be obtained on a screen. (T/F)$$(e)$. A concave mirror always forms a real image. $(T/F)$

$(a)$. We can obtain an enlarged and erect image by a convex mirror. $(T/F)$

False

Explanation:

A convex mirror has the ability to form an image of an object spread over a large area if the object is placed at a larger distance. A convex mirror always forms a virtual, upright, and diminished image of the objects.

$(b)$. A concave lens always forms a virtual image. $(T/F)$

True

Explanation:

The image formed by a concave lens is always virtual, erect, and smaller in size than the object. It is diverging in nature.

$(c)$. We can obtain a real, enlarged, and inverted image by a concave

mirror. $(T/F)$

True

Explanation:

A real, enlarged, and inverted image of the object can be obtained by a concave mirror if the object is placed between the center of the curvature and the focus of the mirror.

$(d)$. A real image cannot be obtained on a screen. $(T/F)$

False

Explanation:

There are two types of images formed by mirrors and lenses-

1. Real image- An image that can be obtained on a screen is called a real image.

2. Virtual images- An image that can't be obtained on the screen is called a virtual image.

$(e)$. A concave mirror always forms a real image. $(T/F)$

False

Explanation:

A virtual, erect, and magnified image of the object can be obtained by a concave mirror if the object is placed between the principle focus and the pole of the mirror.
