How do you find the focus point of a concave mirror?
Explanation:
- f:focal point.
- R:the center of curvature.
- i:distance between image and vertex(mirror’s center)
- o: distance between object and vertex.
- f=R2.
- or.
- 1f=1o+1i.
- 1f=i+oi⋅o.

And end the mayor therefore. The radius is always going to be twice the focal length.
How will you find the focus and focal length of a concave mirror?
By obtaining the Real image of a distant object at its focus, the focal length of the concave mirror can be estimated as shown in the diagram. The focal length of the convex mirror is positive, whereas that of the concave mirror is negative. The same can also be proved by using the mirror formula: (1/f = 1/v +1/u).
Which type of focus a concave mirror have?
Convex mirror has virtual focus or concave mirror has real focus.
How do you find the focus of a convex mirror?
You can measure the radius of curvature (R) of the mirror by measuring the distance between convex mirror and the screen placed behind the mirror. You can calculate the focal length of the mirror using the equation f = R/2.
Where is the focal point of a convex mirror?
The mirror has a focal point (F) that is located along the principal axis, midway between the mirror’s surface and the center of curvature. Note that the center of curvature and the focal point are located on the side of the mirror opposite the object – behind the mirror.
How do you find center of curvature?
In geometry, the center of curvature of a curve is found at a point that is at a distance from the curve equal to the radius of curvature lying on the normal vector. It is the point at infinity if the curvature is zero. The osculating circle to the curve is centered at the centre of curvature.
How do you find the center of curvature?
3. Calculate the radius of curvature at the point (1,1) on the curve whose equation is x3 − 2xy + y3 = 0 and hence obtain the co-ordinates of the centre of curvature. x = 1 + sinθ and y = sinθ − 1 2 cos 2θ and hence obtain the co-ordinates of the centre of curvature.
How do you find the focal length of a concave lens?
You can calculate the focal length (F) of combination of lenses using the formula F = uv/(u+v). The focal length of convex lens (f1) is shown inside the simulator window. You can calculate the focal length of the concave lens using the formula f2 = (f1F/(f1-F).

What is focus of concave and convex mirror?
For a concave mirror :-The rays traveling parallel to the principal axis of a mirror after reflection pass through (converge at) a point F This point F is known as the principal focus of the concave mirror. It is a real point in front of a mirror. This point F is known as the principal focus of the convex mirror.
Does concave mirror has real focus?
In a concave mirror all the incident rays parallel to principal axis actually pass through the focus F after getting reflected from the concave mirror. Thus concave mirror has a real principal focus.
