Reflection

Definition

Reflection is the change in direction of light when it bounces off a surface. It is crucial for the visualization of microscopic structures in microbiology.

5 Must Know Facts For Your Next Test

1. Reflection occurs when light waves encounter a barrier and are redirected.
2. The angle of incidence equals the angle of reflection, which is known as the law of reflection.
3. Reflection can affect the contrast and clarity of images seen through a microscope.
4. Smooth surfaces, like mirrors, create regular reflection, while rough surfaces cause diffuse reflection.
5. Understanding how light reflects off different media helps in designing better microscopes.
