Q&A

• How does light dispersion contribute to the bending of colors?

  Light dispersion, frequency, and energy collectively determine the bending of colors, with violet having the shortest wavelength and highest bending. A prism, in particular, can separate white light into seven colors through dispersion.

• What does optical density measure, and how is it observed in everyday phenomena?

  Optical density measures a material's ability to slow down light, resulting in refraction. This phenomenon is observed in everyday situations, such as a pencil appearing bent in water. Refraction occurs when light travels from a less dense to a denser medium, leading to a bending effect towards the normal line.

• How are light colors arranged by energy?

  The arrangement of light colors is determined by the energy, including factors such as frequency and wavelength. The concept of refraction and its impact on the perception of objects, especially underwater, is also explained in the video.

• What does light passing through a prism create?

  Light passing through a prism creates a spectrum of colors called ROYGBIV, which is a result of dispersion and refraction. Objects such as prisms, mirrors, and water can all disperse light, contributing to the creation of colorful spectrums.

• How are colors formed?

  Colors are formed through the absorption or reflection of light wavelengths. Each color in the visible spectrum has its own specific wavelength, contributing to the formation of diverse colors.
