Flashcards in Light: Chapter 1.11 and 1.12 Deck (22)
Light has which properties?
What is the wavelength range of Visible Light?
~390 to 700 nm
Light is slower in which medium?
What is the Law of Reflection?
θr = θi
What is Snell's Law in Refraction?
n1sinθ = n2sinθ
In what direction does light travel?
Left to right
What happens to the curvature with a Diverging Lens?
It is lost due to the increase in radius
How is the curvature with a Diverging Lens?
What happens to the curvature with a Converging Lens?
It is gained due to the decrease in radius
List equation that describes relationship between wavelength and frequency:
λ = c/f
Frequency is in what units?
Cycles / s or Hz
What is equation used to determine the speed of light?
v = c / n
What is the equation used to determine wavelength of a particular material?
λm = λ / n
Most of the eye's optical power is in the
The Optical Power of the eye is the function of
- Curvature of cornea
- Change of index
The point source of light functions to emit rays which are
Perpendicular to the wavefront
What happens to the wavefronts as we stray from the light source?
The wavefronts flatten at optical infinity, forming parallel light or collimated rays
What is the equation for Curvature (meters)?
1 / Radius
What is the unit of Diopters?
Myopes use which lens?
Hyperopes use which lens?
