Which of the following is an amplifying instrument?

Solution:

The question asks to identify an amplifying instrument from the given options. Let's analyze each option:

• Microscope: A microscope is an instrument used to see objects that are too small to be seen by the naked eye. It magnifies these objects, thus amplifying their apparent size.
• Tripod: A tripod is a three-legged frame used as a platform for cameras or other equipment to stand on. It does not amplify anything.
• Stage: In the context of a microscope, the stage is the part where the slide is placed. It does not amplify.
• Tube: In the context of a microscope, the tube connects the objective lens to the eyepiece. It is part of the optical path but not an amplifying instrument itself.

Based on the functions, a microscope is the instrument that amplifies the size of small objects.

Answer: microscope
