On the informational level, the student becomes acquainted with the law of reflection as it pertains to plane mirrors. First, the student experiences how a plane mirror creates an image that is flipped from left to right. Second, the law of reflection is used to explain the position of an image seen in a mirror in using a toy. The reflection of the toy appears to be behind the mirror! This is due to the fact that our brain tells us that light travels in straight lines coming from the toy, but when we see the toy reflected in the mirror, this is not actually the case. We are fooled when we perceive the cat as being behind the mirror. What we see is called a virtual image.
How does a person's mirror image differ from their actual image? How are virtual images constructed?
