What is the focal length of concave mirror whose radius of curvature is 40cm?

As focal length is half of the radius of curvature, focal length=40/2 cm =20cm.

Are concave mirror is a part of sphere of radius 40 cm What is the focal length of the mirror?

therefore ,focal length of concave mirror is 20cm.

How do you find the focal length of a concave mirror when radius of curvature is given?

The focal length of a spherical concave mirror is given as $f=\dfrac{R}{2}$, where R is the radius of curvature of the mirror. It is given that $R=24cm$.

What will be the focal length of a concave mirror having radius of curvature 20cm?

Hence, the focal length of the given spherical mirror is 10 cm.

What is the power of a convex lens of focal length 40cm?

So, Power of convex lens is + 2.5 D.

What is the radius of curvature of a concave mirror?

Hint:The radius of curvature of convex or concave mirror is equal to two times of the focal length of convex or concave mirror. The radius of curvature is the radius of sphere formed by the convex or concave mirror. It is also equal to the distance between the pole and centre of curvature.

What is the radius of curvature of plane mirror?

infinite
Radius of curvature of a plane mirror is infinite.

What is radius of curvature of concave mirror?

The distance from the vertex to the center of curvature is known as the radius of curvature (represented by R). The radius of curvature is the radius of the sphere from which the mirror was cut. In fact, if some light from the sun were collected by a concave mirror, then it would converge at the focal point.

What is the radius of a concave mirror?

What is the focal length of a convex mirror whose radius of curvature is 32cm?

So, according to your question the radius of curvature of a convex mirror is 32cm. 16 cm. So the focal length of the convex mirror is 16cm.

What is radius of curvature of concave mirror Class 10?

The distance from the vertex to the center of curvature is known as the radius of curvature (represented by R). The radius of curvature is the radius of the sphere from which the mirror was cut. Finally, the distance from the mirror to the focal point is known as the focal length (represented by f).

What is the power of focal length 40cm?

The focal length of a concave lens is equal to -2.5 D Hence in the above case it is given that the focal length is 40cm or 0.4m. So the power =- 1/0.4= -2.5D the sign is used to determine the type of lens used.
