## What is minimum radius of curvature?

The minimum curve radius is a limiting value of curvature for a given design speed. ▪ In the design of horizontal alignment, smaller than the calculated boundary value of minimum curve radius cannot be used. Thus, the minimum radius of curvature is a significant value in alignment design.

## What is the radius of curvature of a mirror?

How far is this converging point from the mirror’s surface if the radius of curvature (R) of the mirror is 150 cm? If the radius of curvature is 150 cm. then the focal length is 75 cm….The Anatomy of a Curved Mirror.

Principal axis Center of Curvature Vertex
Focal Point Radius of Curvature Focal Length

What is the radius of a flat mirror?

infinite
Hence the radius of the curvature of the plane mirror is infinite.

How do you find the minimum radius?

Step 1: Divide the depth by 2. Step 2: Square your length. Step 3: Multiply the depth by 8. Step 4: Divide the result from step 2 by the result from step 3.

### What is PC and PT?

PC = Point of Curve. PT = Point of Tangent.

Difference Between Radius and Radius of Curvature Radius refers to the distance between the center of a circle or any other point on the circumference of the circle and surface of the sphere. While on the other hand, the radius of curvature is the radius of the circle that touches the curve at a given point.

Is radius of curvature equal to centre of curvature?

Answer: No, a centre of curvature and the radius of curvature is not the same.

How do you find 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.

#### How do you calculate PC and PT?

After the length of the curve (L) and the semi-tangent length (T) have been computed, the curve can be stationed. When the station of the PI is known, the PC station is computed by subtracting the semi- tangent distance from the PI station. (Do not add the semi-tangent length to the PI station to obtain the PT station.

#### What is the radius of curvature of a mirror Class 10?

10 cm. 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 mirror curvature?

It can also be defined as the spherical distance between the point at which all the rays falling on a lens or mirror either seems to converge to (in the case of convex lenses and concave mirrors) or diverge from (in the case of concave lenses or convex mirrors) and the lens/mirror itself.
