Comparing Light and Electron Microscopes

What type of microscope is commonly used in classrooms?

• Infrared microscope

• Ultraviolet microscope

• Light microscope

• Electron microscope

What is the main advantage of using light microscopes?

• They use electrons for imaging

• High resolution

• They are inexpensive and easy to use

• They can visualize large samples

What unit is used to measure the wavelength of light in microscopy?

• Micrometers

• Nanometers

• Millimeters

• Centimeters

What limits the resolution of light microscopes?

• The wavelength of light

• The power source of the microscope

• The type of specimen being observed

• The size of the microscope

What is the maximum resolution of a light microscope?

• 0.1 nanometers

• 0.2 micrometers

• 2.0 micrometers

• 1.0 micrometers

Why are electron microscopes not commonly used in classrooms?

• They are easy to use

• They are very expensive

• They use light for imaging

• They are too small

What is the main reason electron microscopes are used primarily by scientists in laboratories?

• They can only visualize dead specimens

• They are not as powerful as light microscopes

• They produce black and white images only

• They require special training to use

What feature of electron microscopes allows them to have a higher resolution?

• The complexity of their use

• Their higher cost

• The use of electrons

• Their larger size

What is the wavelength of electrons used in electron microscopes?

• 1.0 micrometers

• 0.1 nanometers

• 2.0 nanometers

• 0.2 micrometers

Why is a smaller resolution value better in microscopy?

• It makes the microscope cheaper

• It indicates stronger magnification

• It allows viewing larger specimens

• It means finer details can be seen
