Optical Instrument Resolution and Introduction to Kimberly Strong and Electromagnetism

In this lecture, we will discuss the resolution of optical instruments, including the minimum spot size and angular separation required for resolution. Additionally, we will introduce Kimberly Strong and the concept of electromagnetism. This reading assignment covers relevant material for the course and includes a masteringphysics pre-class quiz.

Presentation Transcript

  1. PHY138 – Last Waves LectureToday’s overview • The Resolution of Optical Instruments • Introduction to Kimberly Strong and Electromagnetism Quarter

  2. Reading Assignment Today’s reading assignment from the text by Knight was: Chapter 23, Section 23.8 (This material is part of the course, and may appear on the final exam in April)

  3. Reading Assignment for January, 2008 Between now and January 7, please read Chapter 25, “Electric Charges and Forces”, Sections 25.1-25.6. There will be a masteringphysics Pre-Class quiz on Chapter 25 material, due Mon. Jan 7 by 10:00 AM.

  4. Resolution • The spot size in an image has a minimum of about 2.5 wavelengths • In order for two spots to be separated, or “resolved”, the corresponding points on the object must have an angular separation of at least (wavelength / lens diameter) • In a microscope, this means points on the object must be separated by more than a wavelength in order to be resolved.
