1. What is the incoming ray called, before it reflects off an interface?
• Ancident Ray (r)

2. What is the angle between the normal and incident ray called?
• Angle of incidence

3. What is the reflected ray called?
• Reflected ray

4. What is the angle between the reflected ray and the normal called?
• Angle of incidence

5. What is an interface?
• A boundry between media

6. What is the material through which light travels?
• Media, pl Medium

7. How does light travel?
• In straight lines

8. What is a beam of light?
• Many rays that are parallel to eachother

9. 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

10. When a beam of light hits a bumbym rough surface, does the reflection preserve or scatter the rays?
• The reflection scatters the rays

11. 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)

12. What is the first thing to draw when showing the reflection from any curved mirror?
• The principle axis (P or PA)

13. 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

14. Doe sthe reflective surface curve inward or outward (like the Balls) in a concave mirror?

It curves inward

15. Does the reflective surface curve inward or outward (like the balls) in a convex mirror?

It curves outward

16. If the object is at the centre of curvature for a concave mirror, will it be real or Virtual?
• Real
