The following image depicts which of the following wave properties? Diffraction, Rarefaction, Dispersion, Interference
Understand the Problem
The question asks you to identify the wave property demonstrated in the image. The image shows white light passing through a prism, resulting in the separation of light into its constituent colors (a spectrum). You need to determine which of the given options best describes this phenomenon.
Answer
Dispersion
The image depicts dispersion, which is the separation of white light into its constituent colors (the visible spectrum) when it passes through a prism.
Answer for screen readers
The image depicts dispersion, which is the separation of white light into its constituent colors (the visible spectrum) when it passes through a prism.
More Information
Dispersion occurs because different wavelengths of light are refracted at slightly different angles by the prism. Violet light (shorter wavelength) bends more than red light (longer wavelength), resulting in the separation of colors.
Tips
A common mistake is confusing dispersion with diffraction. Diffraction involves the bending of waves around obstacles or through openings, while dispersion involves the separation of waves based on their frequencies.
