Select the statement which correctly describes the relationship between magnification, image size, and actual size.
Responda
Magnification = image size x actual size
Image size = magnification x actual size
Actual size = magnification x image size

[blank_start]Laser scanning[blank_end] microscopes work by scanning an object with very high resolution using a laser beam, which is analysed by a computer to form an [blank_start]image[blank_end]. While expensive, these microscopes produce high r[blank_start]esolution[blank_end], high c[blank_start]ontrast[blank_end] images that can also be [blank_start]3[blank_end]-dimensional.

Questão 5
Questão
[blank_start]Electron[blank_end] microscopes emit a wavelength of radiation of about [blank_start]0.004[blank_end] nanometers, resulting in a very high [blank_start]resolution[blank_end]. They are also able to [blank_start]magnify[blank_end] images much more than other types of microscope. During the process, [blank_start]electrons[blank_end] are 'spat out' by a [blank_start]cathode[blank_end]. Instead of a glass lens to focus the image in other types of microscope, the [blank_start]electron[blank_end] microscope uses a [blank_start]magnet[blank_end]. When the electrons reach the sample, some pass [blank_start]through[blank_end] it and some bounce off, depending on whether the microscope is [blank_start]scanning[blank_end] (SEM) or [blank_start]transmission[blank_end] (TEM).
