Final answer:
The statement regarding CR receptors is false, as smaller pixel sizes in receptors yield higher spatial resolution, not larger ones. On the other hand, electron microscopes can indeed resolve smaller structures than light microscopes due to the shorter wavelengths of electrons.
Step-by-step explanation:
The statement about CR (Computed Radiography) receptors is false. Larger receptors do not provide the best spatial resolution. In fact, spatial resolution improves with smaller pixel sizes. For CR receptors, this relates to the phosphor plate's ability to capture finer details. When the pixel size is smaller, the receptor can resolve smaller structures, providing higher resolution images.
As for electron microscopes, the statement provided in the student's question is true. Electron microscopes have a much higher resolving power than light microscopes, meaning they can resolve much smaller details. This is because electron microscopes use a beam of electrons instead of light and the wavelength of electrons is much shorter than that of visible light, which allows it to resolve structures that are several magnitudes smaller.
