Characteristics of an optical image formed by a plane mirror
•The image us laterally inverted left to right, up and down
•The image is upright
•Virtual image is the same size as the actual object
•Distance from the object to the mirror is the same to the distance
•angle of incidence
State the law of reflection
The angle of incidence and the angle of reflection is always equal/always the same size
The incident Ray,the reflected Ray and the normal line all lies on the same place
Nb! An image cannot be seen when the angle of incidence and angle of reflection are not equal
Regular reflection
•Angle of incidence is equal to angle of reflection
•parallel incident rays are reflected parallel to each other, eg, reflection by a plane mirror
