Properties of light

Definition

Properties of light refer to the characteristics that define how light behaves, including reflection, refraction, and diffraction. These properties are crucial for understanding how microscopes magnify and resolve images.

5 Must Know Facts For Your Next Test

1. Light travels in straight lines until it interacts with an object or medium.
2. The wavelength of light determines its color and is inversely proportional to its energy.
3. Refraction occurs when light passes from one medium to another, changing its speed and direction.
4. Diffraction happens when light waves encounter an obstacle or slit that is comparable in size to its wavelength.
5. Microscopes use lenses to manipulate the properties of light to magnify tiny objects.
