ESSAY PART:
A group of students of students wantsto build an apparatus that produces a mirage of an object. For thispurpose, they need to know the radius of curvature of the concavemirror they are using. Please explain how they can achieve theirgoal? Make sure to indicate variables, equipment necessary andpossible procedure. (10pts) Also on the space labeled Experimentalsetup sketch your apparatus.
Experimental Setup: (5 pts)
- The students completed their corresponding measurements andobtained the following data:
Distance to the object (cm) | 10 | 15 | 20 | 25 | 30 | 35 |
Distance to the image (m) | 30 | 15 | 12 | 10.7 | 10 | 9.5 |
| | | | | | |
| | | | | | |
Complete the above table bymanipulating the data so that you are able to determine the focallength of the mirror. (20pts)
- Graph your manipulated data. (20 pts)
- Write the mathematical equation describing the relationship.Explain the physical meaning of the slope and the y-intercept. (30pts)
