1. Light is incident in the flat surface, making an angle of 10 with the surface, what is the angle of
incidence? What is the angle of reflection?
A. The angle of the incidence 10 and the angle of reflection is 10.
B. The angle of incidence is 20 and the angle of reflection is 20.
Answer:
The question requires
only one response which
makes a unistructural.

Answer 1:
The question would
fall to relational
since the student
will require to look
for a relationship of
the object and
image on the given
figure.
As you can see, the
rays of light that
pass through the
lens are parallel to
the principal axis.
This means that
they never intersect,
and therefore, no
real image is
formed. However,
the appearance of
an image is created
because the rays
appear to diverge
from a point behind
the lens. This point
is called the virtual
image.

2. Which of the following statements accurately explains the image formed by a diverging lens when the object
is located between the focal point and the lens?

A.
B.
C.
D.
Answer: C
Real, upright, enlarged
Real, inverted and enlarged
Virtual, upright and enlarged
Virtual, inverted and enlarged
The virtual image
formed by a
converging lens
when the object is
located at the focal
point is always
upright and
demagnified. This
means that the
image has the same
orientation as the
object, and it is
smaller than the
object.
Answer 2:
The question would
fall to relational
since the student
will require to look
for a relationship of
the object and
image on the given
figure.
As you can see, the
rays of light that
pass through the
lens diverge,
meaning they
spread out. This
means that they will

never intersect, and
therefore, no real
image is formed.
However, the
appearance of an
image is created
because the rays
appear to diverge
from a point behind
the lens. This point
is called the virtual
image.
The virtual image
formed by a
diverging lens when
the object is located
between the focal
point and the lens is
always upright and
enlarged. This
means that the
image has the same
orientation as the
object, and it is
larger than the
object.
