Final answer:
The statement that any color mode can be used for printing is false; specific color modes like CMYK for ink jet printers are necessary. Relief printmakers employ multiple blocks or a single block in the reduction method to create multicolored prints. Visible light isn't the only radiation type to cause the photoelectric effect, and a current in a photoconductive cell requires multiple expelled electrons.
Step-by-step explanation:
The statement, "For printing, you can use any color mode," is false. The correct statement would be that different printing processes require specific color modes for optimal results. For instance, ink jet printers typically use a color mode that consists of cyan, magenta, yellow, and black (CMYK) to create a wide range of colors on paper. Similarly, color televisions also use primary colors, but through the Red-Green-Blue (RGB) color model, which involves combining light in different colors to produce the desired color on the screen.
Relief printmakers may use multiple blocks or matrices for printing different colors, or a single block in a reduction print method, where parts of the block are cut away as the printmaking process continues. These methods allow the creation of prints with multiple colors.
Additionally, visible light is not the only type of electromagnetic radiation that can cause the photoelectric effect. The statement that visible light is the only type capable of causing this effect is false. Moreover, it is also false that a current is created in a photoconductive cell if only one electron is expelled from a photon strike; a current is established only when numerous electrons are expelled and can flow.
