Things to Learn Concave mirrors and convex mirrors Construction rules for curved mirrors Formation of images Uses of curved mirrors

Convex Mirrors CF Focal Length(FP) = R/2 Center of Curvature R Radius of Curvature Focus P Pole Shiny Surface
(I) Concave Mirror FC 1.
(II) Convex Mirror FC 1.
Activities #1 Hold a concave mirror about 10cm away from you. Observe your image. The image formed is magnified and erect.
Activities #2 Now ask your partner to hold the mirror and slowly walk away. Observe the change of the image. The image becomes diminished and inverted.
Conclusion The nature of image depends on the position of object.
(1) Object behind C FC Image: Between C and F Nature: Inverted, diminished, real.
FC Image: At C Nature: Inverted, same size as the object, real. (2) Object at C Try yourself !
FC Image: Behind C Nature: Inverted, magnified, real. (3) Object between C and F Try yourself !
(4) Object at F F Image: At infinity C Parallel beam Try yourself !
(5) Object between F and the mirror Image: Behind the mirror Nature: Erect, magnified, virtual. FC Try yourself !
Convex Mirror FC Image:Behind the mirror Nature: Erect, diminished, virtual.
Concave Mirrors 1. Shaving Mirrors / Make-up mirrors Image of the face is magnified
Concave Mirrors 2. Reflectors
Concave Mirrors 3. Reflecting telescope
Convex Mirrors 1. Rear-view Driving Mirror It gives a wider view than plane mirror.
Convex Mirrors 2. Surveillance Mirrors
Optics Curved Mirror Real or Virtual 1. A real image is formed by the intersection of light rays from a pint of the object. 2. The term ‘virtual” is.
Curved Mirrors Chapter 14, Section 3 Pg
Learning Outcome Draw a ray diagram to find the position, nature and size of the image produced by a concave and convex mirrors.
The image formed by concave mirror. The image formed by concave mirror depends on the position of the object in front of the mirror. As we will see later.

The sign on the magnification is related to the orientation of the object and resulting image.
SPHERICAL MIRRORS What is a spherical mirror? Spherical mirrors are mirrors whose surfaces form a part of a hollow sphere, The spheres can be made of.
Spherical Mirrors Spherical mirror – a section of a sphere of radius R and with a center of curvature C R C Mirror.
Properties of Reflective Waves Curved Mirrors. Image close to a concave mirror appear:
Principal axis FCC Image Characteristics Real Inverted f < d i < 2f h i < h o Any incident ray parallel to the principal axis will reflect through the.
Spherical Mirrors Alfano I: Year 4. Concave Mirrors Concave mirrors are a type of spherical mirrors. We see them used as make-up mirrors or shaving mirrors,
Concave Mirror The center C of a concave mirror is outside the mirror. Focal point F is also outside the mirror, half way between the center and the surface.
Reflection & Mirrors. Reflection The turning back of an electromagnetic wave (light ray) at the surface of a substance. The turning back of an electromagnetic.
Sections 11.5 & There are three basic types of mirrors: plane, concave, and convex Light rays behave differently when they reflect from curved mirrors.

Properties of Reflective Waves Curved Mirrors. Image close to a concave mirror appear: Larger than the object Upright.
Reflection from Curved Mirrors. 2 Curved mirrors The centre of the mirror is called the pole. A line at right angles to this is called the principal axis.
Mirror Equation Ray diagrams are useful for determining the general location and size of the image formed by a mirror. However, the mirror equation and.

1 Reflection and Mirrors. 2 The Law of Reflection “ The angle of incidence equals the angle of reflection.”
Sign rules (from your book) S>0 when object is on the incoming side of the lens or mirror S’>0 when the image is on the outgoing side of the lens or mirror.
Curved Mirrors. Two types of curved mirrors 1. Concave mirrors – inwardly curved inner surface that converges incoming light rays. 2. Convex Mirrors –
Ch18.1 Mirrors Concave mirror All light rays that come in parallel to the optical axis, reflect thru the focal point. All light rays that come in thru.
LIGHT. WHAT IS LIGHT? Light is a form of energy that travels away from the source producing it at a speed of 3 x 10 8 m s -1.
Unit 8 – Curved Mirrors. Unit 8 – Concave Spherical Mirror Concave spherical mirror: a mirror whose reflecting surface is a segment of the inside of a.
Plane Mirror: a mirror with a flat surface Plane mirrors create virtual images. A virtual image is a point at which light rays appear to diverge without.
