In the setup shown below the focal length of the given concave mirror ...
Explanation:
To obtain a sharp image, the screen should be placed at the focal point of the concave mirror.
Step-by-Step Solution:
1. Identify the given concave mirror's focal length as 4 cm.
2. Use a ruler to measure the distance between the concave mirror and the object. Assume the distance to be 10 cm.
3. Use the formula 1/f = 1/v + 1/u, where f is the focal length, v is the distance from the mirror to the image, and u is the distance from the mirror to the object.
4. Substituting the values given, we get 1/4 = 1/v + 1/10.
5. Solving for v, we get v = -20 cm.
6. The negative sign indicates that the image is formed behind the mirror, which means it is a virtual image.
7. Now, we know that the screen should be placed at the focal point of the mirror to obtain a sharp image.
8. Since the focal length is 4 cm, the screen should be placed 4 cm away from the mirror.
9. Mark the position and place the screen at that point.
10. Adjust the position of the screen until a sharp and clear image is obtained.
Therefore, the screen should be placed 4 cm away from the concave mirror to obtain a sharp image.
To obtain a sharp image, the screen should be placed at the focal point of the concave mirror.
