Описание: When light reflects off a plane mirror, it does so according to the law of reflection: the angle of incidence (the angle at which light strikes the surface) is equal to the angle of reflection (the angle at which light bounces off). The image formed by a plane mirror is virtual (meaning light rays don't actually pass through it), erect (upright), and the same size as the object. 

Here's a more detailed explanation:

Key Concepts:

Angle of Incidence (θi):

The angle between the incoming light ray and the normal (a line perpendicular to the mirror's surface at the point where the light hits). 

Angle of Reflection (θr):

The angle between the reflected light ray and the normal. 

Virtual Image:

An image that appears to be at a certain location but is not actually formed by light rays passing through that point. The light rays appear to originate from the image. 

Erect Image:

An image that is upright, meaning it is not inverted compared to the object. 

Image Characteristics:

Virtual: The image is located behind the mirror, and the light rays only appear to come from that location. 

Erect: The image is not inverted vertically. 

Same Size: The image is the same size as the object. 

Same Distance: The image is located the same distance behind the mirror as the object is in front of the mirror. 

Lateral Inversion: The image is reversed left to right (e.g., a left hand in the object will appear as a right hand in the image). 

In simple terms: Imagine you're standing in front of a mirror. When you look at your reflection, you see an upright, same-sized, and reversed version of yourself. This is because the light from your body is bouncing off the mirror, and your brain interprets
