Question

the radius of curvature of concave mirror is -12cm.then,the focal length will be​

Answer 1

AnsWer :

- 6 cm.

GiveN :

• The radius of curvature is - 12 cm.

To FinD :

The focal length.

SolutioN :

• The radius of Curvature of Concave mirror is - 12 cm.

☯ We have, Formula.

→ F = R / 2.

✎ Where as,

• F focal length.
• R Radius of Curvature.

$\rule{90}2$

→ F = - 12 / 2.

→ F = - 6 cm.

Therefore, the of the focal length is - 6cm.

MorE Information.

● Mirror Formula :

→ 1 / f = 1/ v + 1 / u.

$\rule{50}1$

● Lens Formula :

→ 1 / f = 1 / v - 1 / u.
