Which type of microscopes was developed most recently? (1 point)

Question

• light-based microscope
• electron microscope
• fluorescence microscope
• scanning tunneling microscope

Answer 1

The scanning tunneling microscope (STM) was developed most recently among the options listed. It was invented in the 1980s, while the other types of microscopes have earlier origins: light-based microscopes date back to the 16th century, electron microscopes were developed in the 1930s, and fluorescence microscopes became more prevalent in the mid-20th century.

Answer 2

Which one came out last

Answer 3

The scanning tunneling microscope (STM) is the most recent of the options listed. It was developed in 1981 by Gerd Binnig and Heinrich Rohrer. The other types of microscopes were developed earlier:

• Light-based microscopes date back to the 16th century.
• Electron microscopes were developed in the 1930s.
• Fluorescence microscopes were developed in the 20th century but became widely used in the 1950s.

So, the correct answer is the scanning tunneling microscope.
