BackHuygens' Principle
States that every point on a wavefront acts as a source of spherical wavelets, forming a new wavefront as a tangent to these wavelets. Wavefront
A surface over which an oscillation or vibration has a constant phase, such as the crest of a wave. Spherical Wavelets
Small, spherical waves that originate from every point on a wavefront, according to Huygens' principle. Diffraction
The bending and spreading of waves when they encounter an obstacle or pass through a narrow aperture. Slit
A narrow opening through which light passes, affecting the degree of diffraction based on its size relative to the wavelength. Wavelength
The distance between successive crests of a wave, determining the degree of diffraction when passing through a slit. Collimated Light
Light whose rays are parallel, and therefore will spread minimally as it propagates. Isotropic Light
Light that spreads uniformly in all directions, often resulting from significant diffraction. Interference Pattern
A pattern of varying intensity resulting from the superposition of waves, such as light passing through slits. Constructive Interference
Occurs when waves combine to produce a wave of greater amplitude, resulting in increased brightness. Destructive Interference
Occurs when waves combine to produce a wave of reduced amplitude, resulting in decreased brightness. Double Slit
An experimental setup where light passes through two slits, creating an interference pattern due to diffraction. Apex
The highest point of a wavelet, used to determine the new wavefront in Huygens' principle. Tangent Line
A line that touches a curve at a point without crossing over, used to form the new wavefront in Huygens' principle. Diffraction Pattern
The pattern of light and dark bands on a screen, resulting from the diffraction and interference of light waves.
