Answer 1

A is the answer
Hope it helps you


Please mark me as brainiest

Answer 2

$\;\qquad\quad\;\;\large{\odot\;\;\underline{\underline{\bf{\purple{Convex\; mirror}}}}}$

1) Reflecting surface is curved outward

2) It is diverging mirror

$\;\mapsto\quad\quad\;\;\underbrace{\bf{\green{uses \: of \: convex \: mirror}}}$

• used as rear view mirror in vehicles .

• used at blind turns on one point of of merging traffic .

• used in shops as security mirror .

$\;\;\;:\rightarrow\;\;\underline{\bf{\orange{Principal\; axis\;:-}}}$

It is the straight-line parring through the pole and centre of curvature of the spherical mirror.

$\;\;\;:\rightarrow\;\;\underline{\bf{\orange{Pole\;:-}}}$

It is the centre of the reflecting surface of a spherical mirror. it is generally denote with P .

$\;\;\;:\rightarrow\;\;\underline{\bf{\orange{Principal \;focus\;:-}}}$

A number of rays which falls parallel to the principal axis after getting reflected and these rays come from a point on the principal axis. it is generally denote with F .

$\;\;\;:\rightarrow\;\;\underline{\bf{\orange{centre\; of \;curvature\;:-}}}$

It is the centre of the sphere formed by the reflecting part of a spherical mirror . it is generally denote with C.
