Focal Length in a Concave Mirror
In the case of a concave mirror, the focal length is considered negative. This is based on the sign convention used in optics, where the focal point is located on the same side as the object.
Image Distance in a Concave Mirror
The image distance is determined by the position of the image in relation to the mirror. For real images formed by a concave mirror, the image distance is positive, as they are formed on the same side as the object.
Object Distance in a Concave Mirror
The object distance is always measured from the mirror's surface to the object. According to the sign convention, the object distance is considered positive if the object is placed in front of the mirror.
Summary of Sign Conventions
To summarize the sign conventions for a concave mirror:
Understanding these conventions is crucial for solving problems related to concave mirrors in optics.
In the case of a concave mirror, the focal length is considered negative. This is based on the sign convention used in optics, where the focal point is located on the same side as the object.
- Focal Length (f): Negative
Image Distance in a Concave Mirror
The image distance is determined by the position of the image in relation to the mirror. For real images formed by a concave mirror, the image distance is positive, as they are formed on the same side as the object.
- Image Distance (v): Positive for real images
- Image Distance (v): Negative for virtual images
Object Distance in a Concave Mirror
The object distance is always measured from the mirror's surface to the object. According to the sign convention, the object distance is considered positive if the object is placed in front of the mirror.
- Object Distance (u): Positive
Summary of Sign Conventions
To summarize the sign conventions for a concave mirror:
- Focal Length (f): Negative
- Image Distance (v): Positive for real images, negative for virtual images
- Object Distance (u): Positive
Understanding these conventions is crucial for solving problems related to concave mirrors in optics.
