Answer #1

Aperature is the size of the hole that lets light into the camera. Measurement of aperature is f-stop where specimen gets focused. The smaller the number, the bigger the hole and the more light and bigger the number, the smaller hole and less light.

Smaller Aperture (2.8)= Wider aperature = More Light.

Larger Aperture (22)= Narrow Aperture = Less Light.

Optics: Interference and Diffraction 1. Why do you think the colors (when light diffracts) appears in different places at all? 2. Why do the colors appear specifically in the order they do? 3. What kind of shape must the diffraction gratings be to produce the diffraction in light? Explain. (answer is rectangular slit grating, but explain why it’s this shape)

Without her glasses, Dr.D.’s myopic eyes can only image objects that are, at most, 18.5cm awayfrom her eye(this is called her “far point”). Her “near point” (the closest she can image an object) is 10.5 cm from her eye. With this range of vision, she obviously needs glasses. Let’s say we want her glasses to allow her to see an object 20 feet away(not really the same as “20/20” vision.... but close enough). You also need to note her glasses...
