Question

diagram of a concave mirror​

Answer 1

Terms Used in Concave Mirror Imaging

1. Incident ray – The ray of light that is incident on the surface
2. Reflected ray – The ray of light that is reflected from the surface
3. Center of curvature – The center of the sphere from which the concave mirror has been constructed
4. Radius of curvature – The radius of the sphere from which the concave mirror has been constructed
5. Pole – The mid-point of the concave mirror
6. Principal axis – An imaginary line that connects the pole and the center of curvature
7. Focus – A point on the principal axis where rays of light that are parallel to the axis converges after reflection
8. Focal length – The distance between the pole and the focus and is one-half of the radius of curvature
9. Object distance – The distance between the object and the pole
10. Image distance – The distance between the image and the pole
