Grade 10 Optics Practice Test

The acronym SALT in the context of images formed by plane mirrors stands for Size, Attitude, Location, and Type. Each component of the acronym helps describe the characteristics of the images produced by mirrors:

- **Size**: This refers to the dimensions of the image compared to the object. In the case of plane mirrors, the size of the image is equal to the size of the object.

- **Attitude**: This element describes the orientation of the image. Plane mirrors produce images that are laterally inverted, meaning the left and right sides are reversed, while the orientation remains upright.

- **Location**: This component indicates where the image is formed relative to the object. In plane mirrors, the image appears to be located the same distance behind the mirror as the object is in front of it.

- **Type**: This refers to the nature of the image, which in the case of plane mirrors, is virtual. Virtual images cannot be projected on a screen and are formed at a location where light rays seem to diverge from.

Understanding these components helps students analyze and predict the characteristics of images formed by plane mirrors in optical experiments.
