a prism is a transparent object with flat, polished surfaces that refract light. Prisms are used to separate white light into its component colors, a process known as dispersion. This is because each color of light has a slightly different wavelength and refracted at a slightly different angle.
Prisms are commonly used in optics and spectroscopy to:
1. Separate light into its color components (spectrum)
2. Measure the refractive index of materials
3. Study the properties of light and color
Some common types of prisms include:
1. Equilateral prism (60° angle)
2. Right-angled prism (90° angle)
3. Dispersion prism
4. Total internal reflection prism
