Activity 8.2 – Science Form 1 Chapter 8

Activity 8.2:
Aim: To determine the characteristics of the image formed by a plane mirror, concave mirror and convex mirror

Materials and apparatus: Plane mirror, concave mirror, convex mirror, candle, graph paper.

Instruction
1. Place a candle on a piece of graph paper in front of a plane mirror as shown in Figure 8.4.


2. Observe the image formed. Is the image the same size, smaller or bigger than the object?

3. Repeat steps 1 and 2 by replacing the plane mirror with a concave mirror and a convex mirror.

4. Record the results in a table.


5. Then, measure the distance of the image from the plane mirror.

Distance of image from the plane mirror = ______________ squares on graph paper.


Questions
1. Compare the size of the image formed in the mirrors with the size of the object.

2. Compare the distance of the image formed in the plane mirror with the distance of the object.

Answer:
1.
Plane mirror: Image size is the same as the object size
Concave mirror: Image size is bigger than the object size
Convex mirror: Image size is smaller than the object size

2. Distance of image formed in the plane mirror is equal to the distance of object from the plane mirror.
