What is the bending of light as it passes the edges of a barrier called?
What is the bending of light as it passes the edges of a barrier called?
Diffraction
Huygens' wavelets combine to form a straight wavefront, except at the edges of the wave. The wavelets spread out in a linear manner when a barrier creates an edge.

False (B)
What happens when a narrow beam of sunlight or white light passes through a glass prism?
What happens when a narrow beam of sunlight or white light passes through a glass prism?
It splits into different colors.
As white light crosses the boundary from air into glass and back into air, its wave nature causes each different color of light to be bent, or refracted, at a different angle.

What is the result of the unequal bending of different colors in white light?

The bending of light waves as they pass the edges of a barrier.
Huygen's principle
Huygen's principle
A model that describes how light waves propagate by considering each point on a wavefront as a source of secondary spherical waves.
Dispersion
Dispersion
The separation of white light into its component colors (red, orange, yellow, green, blue, indigo, violet) due to different wavelengths being refracted at different angles.

Study Notes
Diffraction
- Diffraction is the bending of light as it passes the edges of a barrier.
Huygen's Wavelets
- Huygen's wavelets combine to form a straight wavefront
- Wavelets spread out in a circular manner when a barrier creates an edge
Light Passing Through a Prism
- A narrow beam of sunlight or white light, passing through a glass prism, splits into different colors.
Refraction of White Light
- White light's wave nature causes each color to refract at a different angle as it crosses a boundary (e.g., air to glass, then back to air).
Formation of a Spectrum
- Unequal bending of different colors results in white light spreading into a spectrum.
Wave Properties of Light
- Light has wave properties
- Each color of light is associated with a specific wavelength.
Visible Light Wavelength Range
- Visible light has wavelengths ranging from approximately 400 nm to 700 nm.
