Microscopy Quiz

What does the term 'microscopy' refer to?

• The observation of visible objects

• The process of making objects smaller

• The science of using microscopes

• The study of large objects

What is the primary function of a lens in a microscope?

• To magnify images of small objects

• To illuminate the specimen

• To focus light on the specimen

• To capture images

What is the relationship between magnification and resolving power?

• Magnification and resolution are unrelated

• Higher magnification can decrease resolution

• Higher magnification always means higher resolution

• Higher resolution is achieved with lower magnification

What is the numerical aperture of a lens?

• The measure of light intensity

• The measure of resolving power

• The distance between the lens and specimen

• The angle of light entering the lens

Which type of microscope uses electrons instead of light?

• Compound Microscope

• Electron Microscope

• Fluorescence Microscope

• Light Microscope

What is the primary advantage of using a Transmission Electron Microscope (TEM)?

• It provides 3D images

• It can achieve very high magnifications

• It is easier to use than light microscopes

• It requires no specimen preparation

What is the purpose of immersion oil in microscopy?

• To reduce light scattering

• To increase the refractive index

• To clean the lenses

• To illuminate the specimen

Which microscopy technique enhances contrast in transparent specimens?

• Fluorescence Microscopy

• Phase-Contrast Microscopy

• Dark-Field Microscopy

• Bright-Field Microscopy

What is the main function of the condenser in a light microscope?

• To adjust the brightness

• To hold the slide in place

• To focus light onto the specimen

• To magnify the image

What type of microscopy uses laser light to produce high-resolution images?

• Bright-Field Microscopy

• Dark-Field Microscopy

• Phase-Contrast Microscopy

• Confocal Microscopy
