What is unique about electron microscopes compared to optical microscopes?

• Moves the objective lens set for general focus

• Turns the light source on and off

Which part of the microscope connects the stage to the tube?

• The base

• The arm

• The lens

• The eyepiece

What are scanning probe microscopes used for?

• Viewing large objects like rocks

• Seeing individual atoms or molecules on a material's surface

• Examining live specimens in water

• Taking photographs of specimens

What happens when light passes through a concave lens?

• It bends and makes objects appear bigger

• It straightens and does not change the object's appearance

• It bends and makes objects appear smaller

• It reflects back without passing through the lens
