mirror Flashcards
The focal length of a spherical mirror
is twice its radius of curvature.
false
A ray of light passing through the
center of curvature retraces its path
after reflection.
true
The pole is the geometrical center
of the sphere of which the mirror
was a part.
false
A concave mirror always forms an
enlarged real image of an object.
false
To draw a ray diagram, we choose
at least two incident rays for
convenience.
true
A virtual image formed by a
spherical mirror is always upright
and located behind the mirror.
true
A virtual, magnified, and upright
image can be formed by a
concave mirror.
true
A convex mirror always forms
virtual and upright images.
true
The real image formed by a concave
mirror is always inverted.
true
When a ray strikes concave or
convex mirrors obliquely at its pole,
it is reflected obliquely.
true
The same type of images will be formed
even after changing the position of the
object from the concave mirror.
false
When light hits an object, every part of
that object reflects light in all direction.
true
A real image can be formed on a
screen.
true
A concave mirror always forms a
virtual image of a real object.
false
The height of the image in plane
mirrors is always the same as the
height of the object.
true
A convex mirror never forms a real
image of a real object.
true
Incident ray leaves the mirror and is
represented by an arrow pointing
away from the mirror.
false
Concave is a curved mirror in which
the reflective surface bulges away
from the light source.
false
Convex mirror is a curved mirror in which the
reflective surface bulges towards the light
source.
true
The image produced by a convex mirror is
always closer to the mirror than it would be
in a plane mirror for the same object
distance.
