Answer
1. Method A is more accurate than Method B because it allows for precise measurement of angles, which is crucial in the study of light reflection.2. Method A is simpler and more accessible than Method B because it does not require any complex equipment, making it easy for students to replicate the experiment anywhere.
Explanation
## Step 1: Understanding the QuestionThe question asks us to compare two methods of investigating the reflection of light by a plane mirror. Method A involves a protractor drawn on paper, while Method B is not described. We are asked to explain two ways that Method A is superior to Method B. ## Step 2: Identifying the Advantages of Method ASince Method B is not described, we need to focus on the potential advantages of Method A. ### Advantage 1: AccuracyThe use of a protractor drawn on paper allows for precise measurement of angles. This is crucial in the study of light reflection, as the angle of incidence equals the angle of reflection. ### Advantage 2: Simplicity and AccessibilityDrawing a protractor on paper is a simple and accessible method. It does not require any complex equipment, making it easy for students to replicate the experiment anywhere.
