Ancident Ray (r) What is the angle between the normal and incident ray called? Angle of incidence What is the reflected ray called? Reflected ray What is the angle between the reflected ray and the normal called? Angle of incidence What is an interface? A boundry between media What is the material through which light travels? Media, pl Medium How does light travel? In straight lines What is a beam of light? Many rays that are parallel to eachother When a beam of light hits a flat, plane mirror, doe steh reflection preserve or scatter the angles between rays? The reflection preserves the angles When a beam of light hits a bumbym rough surface, does the reflection preserve or scatter the rays? The reflection scatters the rays What are the characteristics of an image, seen in a plane mirror? The object and image are the same size (S)The image is seen behind the mirror (For)The distance is equidistant (Equid)The image is laterally inverted (I)And the image is virtual (V) What is the first thing to draw when showing the reflection from any curved mirror? The principle axis (P or PA) Steps to draw reflection from a curved mirror: 1) Principle Axis2) Mirror Line3) Mirror4) Focus, Centre of curvature5) Object on Principle Axis6) 1st ray of light from top of arrow, running parallel to PA, reflects through the primary focusAll othe rrays are drawn Doe sthe reflective surface curve inward or outward (like the Balls) in a concave mirror? It curves inward Does the reflective surface curve inward or outward (like the balls) in a convex mirror? It curves outward If the object is at the centre of curvature for a concave mirror, will it be real or Virtual?
