Chapter 3: Mirrors Please remember to photocopy 4 pages onto peerless sheet by going A3?A4 and using stomach to back on the photocopier. Reflection is defined as the bouncing of white off an fair game When light hits off most general objects it scatters in all directions this is known as diffuse reflection, notwithstanding when the surface it shines off is flat and silvered a plane mirror then it behaves in a much more sure way. In fact, we can say twain things for definite well-nigh it; these both things are known as The Laws of Reflection of pass. Laws of Reflection of Light 1. The incident ray, the normal at the even of incidence and the reflected ray all lie on the comparable plane. 2. The angle of incidence is equal to the angle of reflection ( = ). The trope formed by a plane mirror is called a realistic stunt man * Spherical Mirrors There are two types of spherical mirror; Concave and Convex. A concave mirror caves in at the centre (as you look at it), whereas a convex mirror bulges out. authorized and Virtual Images* A Real Image is an image formed by the actual ford of light rays. A reliable image can be located on a screen. A virtual image is formed by the apparent cut acrossion of light rays.



A virtual image cannot be formed on a screen (because there are no actual rays to intersect behind the mirror) Concave Mirrors ray plats In order to knock out what an image of an object will look give care after reflection from a spherical mirror, we draw two or three lines following simple rules, and where these lines intersect represents the dress of the image. You should be able to draw a ray diagram showing how a concave mirror forms an image of an object which is placed (i) outside the focus resulting in a real image (ii) inside the focus resulting in a virtual image Three Rules* Parallel and focal point: From peak of object to mirror (parallel to principle axis) and back with focal point. Focal point and parallel: From top of object through focal point and back parallel to...If you want to frustrate a full essay, order it on our website: Orderessay
