If the aperture in a pinhole camera is made smaller, what factor needs to increase for the picture to develop.
What is Exposure time.
100
Mirrors are an example of an optical device that exhibits this boundary interaction when interacting with light.
What is reflection.
100
The rays normally emitted from a light source follow what geometrical path?
What is spherical
100
Shaped transparent material that bends light.
What is lens
100
The reproduction of an object with light.
What is Image.
200
What two things change about the orientation of an image formed through a pinhole camera.
What is flipped upside-down, right-left
200
When light is reflected from a boundary the angle of incidence is the same value as the angle of reflection, but reflected about this line.
What is normal
200
When light rays transmit from one material to another, bending at the boundary.
What is refraction
200
At this point the light rays all come together (possibly for burninating).
What is the focal point
200
Series of optical devices that are used to create an "picture" from an object.
What is an optical system.
300
What is the only thing that can increase the clarity of an image produced through a pinhole camera.
What is decrease the size of the hole.
300
When light encounters a boundary and bounces off in many directions and does not form a clear image. That type of reflection is called:
What is diffuse
300
Materials that don't allow light rays to transmit through them are this.
What is opaque.
300
In this type of lens light rays come together at a single point.
What is converging.
300
When the picture representation of an object can be projected onto a screen.
What is real image.
400
How many rays from each point of the object reach the detector in a pinhole camera?
What is 1
400
In this type of mirror the object appears larger, closer, and the depth of view will be reduced.
What is concave
400
The ratio of the speed of light in materials to the speed of light in vacuum, represented by the value: n is called this.
What is index of refraction
400
This quantity can make an image appear larger or smaller then the object it is representing.
What is magnification
400
When the "picture" created from an object cannot be projected onto a screen.
What is a virtual image.
500
The term that means that a pinhole camera has no focus.
What is infinite field of depth
500
In this type of mirror the object will appear smaller, the depth of view will be larger, the object will appear farther away.
What is convex
500
If the following is true for two materials: n1< n2 which direction will the light ray transmitting from material 1 to material 2 bend?
What is toward the normal
500
In order to draw ray diagrams and use the mathematics for this unit we need to make this approximation that the lens of interest is a strait line.
What is thin lens approximation.
500
An approximation about light can be made when the materials being used are significantly bigger then the wavelength of light used. This brand of optics is called:
