Optics Quest Flashcards
Ordinary light experiences wavelengths in all directions because…
It hasn’t been passed through a polarized filter
When light travels from water to air??
It will bend around the normal
An incident light ray and reflected light Ray experience…
The same medium, angle, and frequency
When light enters a denser medium it’s angle of refraction is ____ than the incident.
Smaller than
When viewing a candle in a plain mirror its image is
Virtual
Water is ____ to UV light and _____ to visible light?
Opaque;traslucent
Why does an image not form on the other side of a diverging mirror?
The light rays never converge
When view an image from an object that is an infinite distance from a converging mirror…
Di=f
When an object is between f1 and f2 its image is??
Magnified
What does it mean to be transparent?
Light is absorbed and transmitted without a loss of energy
What does it mean to be translucent?
Some light is absorbed, some is transmitted, and some is reflected
What does it mean to be opaque?
Light is turned into kinetic energy OR reflected
Light in air bends towards the normal, light in water bends away from the normal, and light moving through water to air bends
Away from the normal
How does light travel?
When observed it travels as a particle… When not observed like a wave
Light bends towards what?
More dense medium
What is snell’s law??
N1 sinø1=n2sinø2
Light normally travels in what direction
Random directions
What happens when light is polarized?
The light vibrates in one direction
For snell’s law what do n1 and ø1 represent?
The incident ray
In snell’s law what do n2 and ø2 represent?
The refracted Ray
What is the first line in a light diagram?
A line from the object to the mirror and then reflected through the focus
What is the second line in a light diagram?
A line from the object through the focus to the mirror reflected as a straight line
In a converging or diverging light diagram what is line 1?
A line from the object to the center of the mirror through the f1 on the other side
In a converging/ diverging light diagram what is line 2?
A line from the object through F1 to the center of the mirror then reflected as straight line
