Question

Explain image formation by spherical mirror in detail(200-300 words)​

Answer 1

Answer:

Rays incident on a spherical mirror exhibits the following behaviour:

Light ray passing through (or directed towards) the center of curvature retraces its path after reflection.

Light ray parallel to the principal axis passes through (or appears to diverge from) focus after reflection.

Light ray passing through (or directed towards) focus is reflected as a ray parallel to the principal axis.

Light ray incident on the pole of the mirror is reflected at an angle of reflection (with principal axis) equal to the angle of incidence (with principal axis).

Answer 2

${\underline{ \red{ \bf Image \: formed \: by \: spherical \: mirror }}}$

◉ Spherical Mirrors,

➣ Concave mirror.

➣ Convex mirror.

$\underline{ \pink{ \bf concave \: miror}}$

➵ We use ray diagrams to find the details of the images formed by a concave mirror , initially supposed to be far away from the mirror is gradually brought nearer to the mirror .

◉ when the object is beyond the centre of curvature ,

➣ when the object is placed beyond the centre of curvature. the image will be formed between centre of curvature and the focus of the concave mirror .

◉ when the object is at the centre of curvature ,

➣ when the object is placed at the centre of curvature . the image will be formed at centre of curvature.

◉ when the object between the centre of curvature and the focus ,

➣ when the object is placed between the centre of curvature and the focus of the mirror the image will be formed beyond the centre of curvature .

◉ when the object is at the focus ,

➣ when the object is at the focus of the mirror the image will be formed at infinity .

◉ when the object is between the focus and the pole,

➣ when the object is placed between the focus and the pole of mirror the image will be formed behind the mirror .

$\underline{ \pink{ \bf convex \: \: miror}}$

➣ in convex mirror there is a permanent rule the placing of object doesn't matter if we place of object anywhere the image formation will be between pole and focus of the mirror .
