When Did Robert Hooke Make His Discovery? Initially discovered by Robert Hooke in 1665, the cell has a rich and interesting history that has ultimately given way to many of today’s scientific advancements. What was Robert Hooke’s first discovery? English physicist Robert Hooke is known for his discovery of the law of elasticity (Hooke’s law),
Why Do You Usually Need To Cut A Very Thin Slice Of A Specimen? Because beams of electrons can only pass through thin samples, cells and tissues must be cut first into ultra thin slices before they can be examined under a transmission electron microscope. Why is it important to cut sections thinly when viewing
Why Should You Use A New Piece Of Lens Paper Each Time You Clean The Lenses? Even Q-tips that have only been used once may have dirt on them that could contaminate the methanol and cause scratches in subsequent objectives or oculars when they are cleaned. … WHEN LENS PAPER IS USED TO CLEAN OBJECTIVES
What Is The Difference Between Wet Mount And Hanging Drop? The wet mount tend to dry out quickly under the heat of the microscope light; it is simpler to perform than the wet mount, but it is useful for short-term observation only. The hanging drop is a more complex technique, but it allows for longer-term
What Is A Stage Micrometer? A Stage Micrometer is simply a microscope slide with a finely divided scale marked on the surface. The scale is of a known true length and is used for calibration of optical systems with eyepiece graticule patterns. What is the role of the stage micrometer in this lab? The stage
What Does A Microscope Do To An Image? Microscopes invert images which makes the picture appear to be upside down. The reason this happens is that microscopes use two lenses to help magnify the image. Some microscopes have additional magnification settings which will turn the image right-side-up. How do light microscopes form images? The light
What Is The Importance Of Proper Handling Of Microscope? Lens and Objective Care – Microscope lenses are very fragile and need to be handled with care to prevent scratches. Never let your lens touch the microscope slide and never touch any of the lens with your fingers. Microscope lenses are difficult to clean and proper
What Was First Used To Look At Cells? It All Started With A Microscope The discovery of the cell would not have been possible if not for advancements to the microscope. Scientist Robert Hooke improved the design of the existing compound microscope in 1665. His compound microscope used three lenses and stage light. It lit
