Physics 2 Flashcards
What is the relationship between the focus and the radius of curvature?
The focal length is half of the radius of curvature
What is a concave mirror? Example
A reflecting surface that bulges inwards
Dentist mirror
What is a convex mirror? Example
A reflecting surface that curves outwards
Security mirrors
What is the focal length?
The distance between the focus and the vertex
What is the radius of curvature?
The distance between the CC and the vertex
Concave mirror where is the image? Object Beyond C At C Between f and c At F Between F and V
Between f and c At C Beyond C No image Behind mirror
At what location in a concave mirror has an upright image?
Between F and V
If an image is behind the mirror is it real or virtual?
Virtual
Salt?
Size bigger or smaller than
Attitude upright or inverted?
Location where?
Type real or virtual?
Convex mirror diagram rule(s)
Same as concave mirrors
In convex mirrors where is the image located?
Between f and v
What are the four rules of reflection in a curved mirror?
A light Ray parallel to the principal axis is reflected through the focus
A light Ray through the focus reflects parallel to the principal axis
A light Ray through the centre of curvature is reflected back on the same line
A light Ray through the vertex is reflected at the same angle
in a convex mirror what is the SALT of the image always?
smaller
upright
behind mirror
virtual
