Physical Optics
The is the name for the bending of light that occurs when rays pass from one medium to another.
What is refraction?
What types of images are produced by a single diverging lens?
Virtual
How fast does light travel?
What is 300,000 km/s?
The opposite of concave.
What is convex?
How does your reflection appear in a concave mirror?
Small and upside down.
The image your eye receives is upside down/right-side up.
Upside Down
This can be used to figure out where an image will be located.
What is a ray diagram?
When a light travels through a convex lens what happens.
What is comes to focal point.
If an object is located inside the focal length of a diverging lens, then compared to the object, the image will be smaller/larger/the same size.
Smaller
Which would use a concave lens? a) car window b) computer screen c) magnifying glass
b) computer screen
This happens to light as it travels through a prism.
Refraction (it bends)
A magnifying glass under water will magnify less/the same/more.
Less (the water scatters the light)
If light traveled at the same speed in glass as it does in air, images through a telescope would look ______________.
The same as they would without the telescope.
The shape of a convex lens.
What is rounds outward?
A convex mirror will form what type of images?
Only Virtual
The color of light that has a wavelength of 510 nm.
What is green? red = 650 (krypton red laser) ; 690 (ruby red); 630 (HeNe) yellow = 570 green = 510 (514 Argon green) blue = 475 violet = 400 UV - e.g. 193 nm for photoablation
A magnifying glass is this type of lens.
Converging or Convex
What instrument is a human eye most similar to: telescope, microscope, slide projector, camera?
Camera
What types of images are produced by a single diverging lens?
Virtual
Concave mirrors can form what type of images?
Real and Virtual
The eyes of people with this condition focus light in front of the retina.
What is nearsighted?
The angle between a ray that strikes a surface and the line perpendicular to that surface at the point of contact.
Angle of Incidence
The change in direction of an electromagnetic wave at a surface that it causes it to move away from the surface.
Reflection
The lens used to correct farsightedness.
What is convex?
An image from which light rays appear to diverge, even though they are not actually focused there; cannot be projected on a screen, and is right side up.
Virtual Image
