Answer 1

Answer:-

$\setlength{\unitlength}{1cm}\begin{picture} \linethickness\linethickness{0.22mm}\put(0,0){\line(1,0){10}}\put(5,0){\vector(0,1){1}}\put(1.5,0){\vector(0,-1){2.9}}\qbezier(6.5,3)(8,0)(6.5,-3)\linethickness{0.25mm}\put(5,1){\line(1,0){2.15}}\qbezier(7.15,1)(6,0)(0.5,-3.5)\qbezier(1,-3.5)(5,1)(6.5,2.85)\put(5.75,-0.11){ \bullet }\put(4,-0.11){ \bullet }\put(6,-0.5){\bf F}\put(3.7,0.3){\bf C}\put(4.8,-0.35){\bf A}\put(4.8,1.3){\bf B}\put(1.7,-3.4){\bf B'}\put(1.3,0.3){\bf A'}\put(7.5,-0.5){\bf P}\put(7.3,1){\bf D}\put(7,2){\bf E}\put(6,1){\vector(1,0){0}}\put(5.8,2){\vector(3,2){0}}\put(2.9, - 2){\vector( - 1, - 2){0}}\put(3.2, - 1){\vector( - 1, - 2){0}}\end{picture}$

The nature of the image formed by concave

mirror when the object is placed between the

focus (f)and center of curvature (c)of the mirror

observed by us is Real , Inverted & enlarged

Hence , Options (c) is the correct answer .

The image is formed between centre of Curvature and Infinity .

Additional Information !!

• Real Image :- The image that can be obtained on a screen is called Real Image

• Real Image is Inverted.

• It formed where light rays actually meet .

• Virtual Image :- The image that cannot be obtained on the screen are called Virtual Image.

• It formed when light rays appears to meet.

• Virtual Image is Erect.

Answer 2

Answer:

$\setlength{\unitlength}</p><p></p><p>{1cm}\begin{picture} \linethickness\linethickness{0.22mm}\put(0,0l</p><p></p><p>{\line(1,0){10}}\put(5,0){\vector(0,1)</p><p></p><p>{1}}\put(1.5,0){\vector(0,-1) {2.9}}\qbezier(6.5,3)(8,0)</p><p></p><p>(6.5,-3) \linethickness{0.25mm}\put(5,1)</p><p></p><p>{\line(1,0){2.15}}\qbezier(7.15,1)(6,0) D}\put(7,2){\bf E}\put(6,1){\vector(1,0) {0}}\put(5.8,2){\vector(3,2){0}}\put(2.9,-2)</p><p></p><p>(0.5,-3.5)\qbezier(1,-3.5)(5,1)</p><p></p><p>(6.5,2.85)\put(5.75,-0.11)</p><p></p><p>{ \bullet }\put(4,-0.11) { \bullet }\put(6,-0.5){\bf F}\put(3.7,0.3)</p><p></p><p>{\bf C}\put(4.8,-0.35){\bf A}\put(4.8,1.3) {\bf B}\put(1.7,-3.4){\bf B'}\put(1.3,0.3){\bf</p><p></p><p>A'}\put(7.5,-0.5){\bf P}\put(7.3,1){\bf</p><p></p><p>{\vector( - 1,-2){0}}\put(3.2, 1){\vector( - 1, - 2){0}}\end{picture}$

When object is placed between focus(f) and Centre of curvature (C) then the image is formed beyond the centre of curvature .

The properties of such a image are —

• Real
• Enlarged
• Inverted

Thus (c) is the correct asnwer.

REAL IMAGE —

A real image is formed when rays of light actually meet at a point . A real image is always inverted and can be obtained on the screen

VIRTUAL IMAGE —

A virtual image is formed when rays do not actually meet at a point but appear to come from a certain point .It Is erect with respect to object and cannot be obtained on a screen

A concave lens can form both type of images
