An important reason for this is that students’ conscious experiences of ‘reflection’ are associated with mirrors and other shiny smooth surfaces.

What is the light source of a microscope?

The most common source for today’s microscopes is an incandescent tungsten-halogen bulb positioned in a reflective housing that projects light through the collector lens and into the substage condenser. Lamp voltage is controlled through a variable rheostat that is commonly integrated into the microscope stand.

What are the examples of natural sources of light?
