What is the incoming ray called, before it reflects off an interface?
-
What is the angle between the normal and incident ray called?
-
What is the reflected ray called?
-
What is the angle between the reflected ray and the normal called?
-
-
What is the material through which light travels?
-
-
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 Axis
- 2) Mirror Line
- 3) Mirror
- 4) Focus, Centre of curvature
- 5) Object on Principle Axis
- 6) 1st ray of light from top of arrow, running parallel to PA, reflects through the primary focus
- All 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?
