b) 400 to 800 nanometers
c) 450 to 650 nanometers
d) 400 to 800 meters (m)

Which color has the longest wavelength?
a) Red has the longest wavelength: 650 nanometers.
Geometric optics includes:
The effects of media on the path of light
When light bounces back from an object, this is known as:
Reflection
In reflection, the light rays that hit the object or interface between media with
different indices of refraction are called:
Incident rays
In optics, a medium (or media, plural) is:
An object through which light passes
When light passes through a transparent medium, it may travel straight through
(Transmission or its path may be altered. This altering or bending property of a
medium is known as:
Refraction
The ray of light that enters a transparent medium is termed:
Incident ray
If light passes through a lens and the rays are spread apart on exiting, this is
known as:
Divergence
If light passes through a lens and the rays are bent toward each other on exiting,
this is known as:
Convergence
A comparison of the speed of light in air to the speed of light through a
substance is:
IR (Snell's Law)
The denser the substance, the more slowly light passes through it, and:
The higher the IR
The IR of crown glass is:
, 1.50
Light travelling through a prism will be bent toward the prism's:
base
The image of an object viewed through a prism:
Is virtual and shifted toward the apex
A 1.00 diopter prism bends light:
1 cm at a distance of 1 m from the prism
A 2.00 diopter prism displaces an object 1 cm at a distance of:
0.5 m
This displacement of an object 4 cm at a distance of 1 m would require prism of:
5.0 diopters
At a distance of 2 m a 12 diopter prism would displace an object:
24 cm
A spherical lens refracts light:
Equally in every direction
A 1.00 diopter spherical lens focuses light at:
1m
The pointer at which a lens forms an image (whether real or virtual is the:
Focal point
All of the following regarding the optical center of a lens is true except:
It always coincides with the geometric center of the lens
The focal length of a lens:
Is the distance between the lens and the focal point
Because the focal point of a minus lens is virtual, the focal length of a minus
lens:
Is likewise virtual
Which of the following is the formula for finding focal length?
P = 1/F
What is the focal length of 5 diopter lens?
0.2 m
A lens has a focal length of 33 cm. What is its dioptric power?
3 diopters
question 30
we good
All of the following regarding cylindrical lenses are true except:
They are plus power lenses
The direction of the line of light as focused by a plus power cylindrical lens:
Is aligned with the axis
Light passing through a cylindrical lens is focused in two lines perpendicular to
each other and separated by an area known as:
Sturm's interval
Light passing through a cylindrical lens is focused in two lines perpendicular to
each other and separated by an area
The light rays in the above-mentioned interval are projected in the shape of a:
Cone
