Question

draw a ray diagram to show formation of image in a convex mirror ​

Answer 1

${ \rm{ \huge{ \bold { \underline{ answer:}}}}}$

Lens :

A Lens is a transparent refracting medium bounded but either two sperichal surfaces, or one spherical surface and the other surface plane.

There are two kinds of lenses :

ㅤㅤㅤㅤ(1) Conves lense

ㅤㅤㅤㅤ(2) Concave lense

Convex mirror : the mirror which bulges inwards.

Concave mirror : the mirror which bulges outwards.

Image is formed through the convex :

I) When object is at infinity — rays are parallel to each other and they are incident on the lens parallel to the principal axis of the lens, which after refraction passed through the second focus. Image formed is real, invited and diminished.

II) When object is at ${\rm{2F_{1}}}$ — From the point of the object, the ray incident parallel to the principal axis, after refraction through the lens, password through the second focus. Image formed is real, inverted and diminished.

III) When object is at ${\rm{F_{1}}}$ — From the pint of the object, a ray parallel to the principal axis after refraction from the lens passes through the second focus of the lens. The other ray incident towards the optical center. The image formed is highly enlarged and formed at infinity.

IV) When object is between lense and focus — From the point of object a ray incident parallel to the principal axis after refraction it passes through the second focus, and other ray through the optical center. Image formed is virtual, erect and magnified
