GUIDE CARD

•Instruction to the user 1.Observed carefully. 2.Study how image formed in the mirror. 3.Do the three activity in the experiment. 4.Study what kind of mirror you may used. 5.Answer the following activity.

Introduction

•How many times do you look at your face in the mirror in one day? •Have you ever thought of how your image is formed in the mirror? •How are you able to see your image?

Objectives

•To learn how the use of mirrors and reflectors. •To study what is the concave mirror and what the convex mirror. •To learn what used of reflection to the mirror.

Pre-Test

Direction:Choose and encircle the best answer.

1.What kind of mirror does reflect in the inner side? a.Concave mirror b.Convex mirror c.Plane mirror d.Circle mirror 2.What kind of mirror does reflect in the outer side? a. Concave mirror b. Convex mirror c. Plane mirror d. Circle mirror 3.They appear to meet at a point behind the mirror called ______ a.Focal length b.Real focus c.Virtual focus d.Principal focus 4.Is the distance from the principal focus to the vertex of the mirror is the ______ a. Virtual focus b. Principal focus c. Real focus d. Focal length 5.Concave mirror and meet or converge at the ________ a. Real focus b. Principal focus c. Virtual focus d. Focal length

Activity card

Activity 1: Images Formed by a Plane Mirror 1.Posistion the mirror at about 7cm from the top of the graphing paper such that the reflecting surface rest on a grid line.Mark this line. 2.Mark a grid line perpendicular to the mirror.Choose a line at the middle.Call this the normal line. 3.Switch on the light source with the slit and position it such that the light ray coming out from the slit (incident ray) hits the surface of the mirror eaxaclt at the normal line.What do you observe? 4.Posistion the source at orient the source such that the ray hits the mirror at an angle at the point where the normal line meets the mirror surface.You will seee two rays.One rays comes from the source as it hits the mirror.This is the incident ray.The other which bounces off the mirror is the reflected ray. 5.Mark with a pencil two points on each of the rays. 6.Remove the light source and trace each ray observed by joining the two points using a pencil and foot rule.

Activity 2: Mirror Image 1.Stand in front of a line mirror. 2.Look at your image.Describe the size of your image compared to your actual size.

3.Move towards the mirror.What do you observe?How far away from the mirror is your image compared to your distance from the mirror?Move away from the mirror.What do you observe? 4.Raise your right hand.What do you see in your image? 5.Describe the nature of the image formed by a plane mirror.

Activity 3: Images Formed by a Driving Mirror 1.Use plane mirror and side mirror to compare their field of view. (Field of view is the area that can be seen in the mirror).Describe the entire field of view of the two mirrors.Compare the images formed by the mirrors. 2.Get someone to stand 5m awawy from the side mirror.Describe the image. 3.Let the person walk towards the mirror.What do you observe about your image? 4The side mirror is the convex mirror.In general described the images formed by a convex mirror.
