Reflection by Spherical Mirrors: Practice Problem & Solution

A light ray traveling parallel to the principal axis of a concave mirror strikes the mirror at angle of incidence q. If radius of curvature of the mirror is R, then after reflection, the ray meets the principal axis at distance d from the centre of curvature, then d is 
R/2
\[\frac{R cos\theta}{2}\]
\[\frac{R}{2cos\theta}\]
\[\frac{R}{2}(1+cos\theta)\]

1. Assertion (A): Radius of curvature of a concave mirror is \(20 \text{cm}\). If a real object is placed in front of a mirror at \(10 text{cm}\) from pole of the mirror, image is formed at infinity. Reason (R): When object is placed at focus of a converging optical system then its image is formed at infinity.  
2. Assertion (A): In case of a concave mirror if a point object is moving towards the mirror along its principal axis then its image will always move away from the mirror. Reason (R): In case of reflection (along the principal axis of mirror) object and image always travel in same directions.  
3. An object is placed in front of a convex mirror of radius of curvature 20 cm. Its image is formed 8 cm behind the mirror. The object distance is :
4. A short linear object of length L lies on the axis of a spherical mirror of focal length ƒ at a distance u from the mirror. Its image has an axial length L' equal to :
5. Assertion (A): The focal length of spherical mirror does not depend on the wavelength of light. Reason (R): The number of wavelengths in the visible region of spectrum are infinite.
