A Ray of light passing through the centre of curvature of a concave mirror is incident on its reflecting surface . What is the angle of incidence and angle of reflection of this ray.

The ray passing through the centre of curvature and strikes the curved reflecting surface makes an angle Zero degree with the normal or 90 degree with the tangent at the point it strikes. This happens because the ray is coming from the center of the sphere of which this curved mirror is the part and in case of circle normal at a point always passes through the centre of the circle. Since the angle of incidence is 0 the angle of reflection is also 0 degree and this ray retraces its path.

- Which mirror is used as a torch reflector?
- Source of light of kept at focus of mirror in headlighte of vehicles give reason
- What is the general value of magnification in lens and mirror
- An object is placed in front of a concave mirror of focal length 30 cm. The virtual image of the object is obtained at a distance 20 cm from the mirror. Calculate the position of the object. Please explain briefly step by step
- The centre of curvature of a covnvex mirror is 20 cm,from the pole of the mirror find its length
- A thin rod of length f/3 is placed along optical axis a concave mirror of focal length f such that its image which is real and elongated just touches rod . calculate the magnification.
- A small candle, 2.5 cm in size is placed at 27 cm in front of a concave mirror of radius of curvature 36 cm. At what distance from the mirror should a screen be placed in order to obtain a sharp image? Describe the nature and size of the image. If the candle is moved closer to the mirror, how would the screen have to be moved?
- What is the importance of magnification. Explain by giving examples.
- I saw in some websites that mirror chapter is removed from the syllabus for 2018-19 and will not come in board exam.So, I want to if ot's true or not(please tell me quickly as I have to read it for exams)
