NAO (Physics) VOLUME 2 CORRECTLY
ANSWERED QUESTIONS.
A group of rays emitted from a small single point on a light source, it requires
a large hole in the second screen?
✔✔Pencil
We use the acronym ROY G BIV to help remember the order of colors. It list
colors from?
✔✔Long wavelengths to short wavelengths
Which wavelength of ultra-violet radiation is absorbed by the ozone layer?
✔✔UV-C
The bending or redirection of a light wave when it passes a barrier without
changing the medium in which it is traveling is called?
✔✔Diffraction
When a light ray travels from one transparent medium to another, it changes
direction. This bending of light, which results from the differences in density
of different transparent materials is called?
✔✔Refraction
When a ray of light travels from one material to another, if its direction of
travel is perpendicular or normal to the interface or junction between the
materials it will?
✔✔change speed by not direction
, When a ray of light travels from a less dense (faster) material to a more
dense (slower) material at an angle to the normal it will?
✔✔bend toward the normal
When a ray of light travels from a more dense (slower) material to a less
dense (faster) material at an angle to the normal it will?
✔✔bend away from the normal
If light travels through a liquid at 140,000 miles per second, what is the index
of liquid?
✔✔1.32
If the optical center of lenses ( except for plano powers) are placed any
place other than directly in front of the patients visual axis...?
✔✔prismatic effect
If a person moves his/her eyes away from the optical center of a lens to the
left in the following RX, what would occur to the patients vision? -1.00 sph
OU
✔✔the patient would be viewing through a base in prism in the right lens
and base out prism in the left lens, but the resulting prism would be equal,
and although the image would be somewhat displaced, there would be no
imbalance
