It made me think, \u201cSo that&#8217;s how you turn a science lesson into something fun!\u201d<\/p>\n<p>By the way, when observing printed materials under a microscope, <b>shining an LED light from the side<\/b> can make the details much clearer. Give it a try! You can really see how different combinations and amounts of these colors produce all sorts of other colors. This is physics in action, and there are so many things that only become apparent when you magnify them under a microscope.<\/p>\n<p>One more thing: even if you are simply looking at the advertisement, you may have trouble focusing unless you place it on a microscope slide. Printed advertisements do not let much light pass through, so depending on the microscope, it can help to use a small penlight to illuminate the sample from above.<\/p>\n<h3>Colored paper and computer screens: is yellow really the same yellow?<\/h3>\n<p>I also decided to take a look at the color of a <strong>colored sheet of paper<\/strong>.
