Converging Lenses

1 / 14

15 Terms

1

Converging Lenses

Thicker in the middle, converge light rays to form real images when rays cross, unless the object is at the focal point or nearer.

New cards
2

Diverging Lenses

Thinner in the middle, diverge light rays, forming virtual images where rays appear to have come from.

New cards
3

Focal Point

Where parallel rays converge or appear to diverge after passing through the lens.

New cards
4

Optical Power

Measured in diopters (D), defined as the inverse of focal length (P = 1/f).

New cards
5

Real Images

Form where rays converge.

New cards
6

Virtual Images

Form where rays appear to diverge.

New cards
7

Magnification

Calculated as the ratio of image height to object height (m = hi/ho = -v/u).

New cards
8

Spherical Aberration

Causes distorted images due to the lens's inability to focus all rays at the same point.

New cards
9

Chromatic Aberration

Results from the lens's inability to bring rays of different colors to the same focus.

New cards
10

Radio Telescopes

Experience less atmospheric interference, enhancing resolution through interferometry techniques.

New cards
11

Resolution

The ability to distinguish separate points, often more critical than magnification.

New cards
12

Reflecting Telescopes

Use converging mirrors as their objectives.

New cards
13

Fiber Optics

Offer advantages over copper, including lower attenuation and immunity to electromagnetic interference.

New cards
14

Ultrasound Imaging

Uses wave propagation and reflection to create images of body tissues.

New cards
15

Magnetic Resonance Imaging (MRI)

Utilizes proton spin resonance in strong magnetic fields to produce three-dimensional images.
