Question

an instrument that uses electrons rather than light to magnify and visualize a sample is called a:
scanning electron microscope
refractive index
glass immersion tank
geiger counter

Explanation:

To solve this, we analyze each option:

• A scanning electron microscope (SEM) uses electrons to magnify samples, unlike light - based microscopes.
• A glass immersion tank is not a device for magnifying samples with electrons.
• The refractive index is a property related to light bending, not an instrument.
• A Geiger counter is used to detect radiation, not for magnifying samples.

So the correct option is the one with "Scanning electron microscope".

Answer:

A. Scanning electron microscope
