Which of the following answers are true: Group of answer choices The larger the slit, the better the wavelength resolution of the spectrometer A slit can select wavelengths spatially. This is for example used in a monochromator, where focused light after refraction in a prism or diffracted from a grating can be selected through a narrow slit. A slit can be used to direct light alternatingly to the sample or the blank. A slit can be used as a photodetector. The narrower the slit, the better the wavelength resolution of t

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
