Answer 1

The law of reflection

Question 2

What is a periscope?

Answer 2

Question 3

What is mirror left right reversal?

Answer 3

It is defined as life reflected from a smooth surface at a definite angle.

Question 8

Multiple images

Answer 8

Multiple images are formed by the reflection that happens when arranging at least two mirrors

Question 9

Characteristics of image formed by a plane mirror:

Answer 9

1. Image is virtual;
2. Same size as the object;
3. Same orientation as the object (upright)
4. Same distance from the mirror as the object

Question 10

What is this based on the characteristics m
1. A ____ is formed when light rays actually meet after reflection.
2. A ___ can be formed on a screen.
3. A ___ is inverted with respect to the object.
e.g. The image of a distance object formed by a concave mirror

Answer 10

Real image

Question 11

What is the based on the characteristics?
1. A ___ is formed when the light rays do not actually intersect after reflection, but they appear the diverge from the mirror.
2. A ___ cannot be formed on a screen
3. A ___ is erect with respect to the object.
e.g. The image on of an object formed by a convex mirror.

Answer 11

Virtual image

Question 12

What is Ray diagramming?

Answer 12

Is a graphical method used to locate the image form by curved mirror.

Question 13

What is a concave mirror?

Answer 13

Reflex light inward to one focal point. It is used to focus what.

Also known as converging mirrors has a reflecting surface that is recessed inwards (away from the incident light)

Question 14

What is a convex mirror?

Answer 14

Is occurred mirror in which the reflected surface bulgest towards the light source.
