12 Questions
What happens to diffraction when the gap size is smaller than the wavelength?
Most waves are reflected
In the diffraction pattern produced by monochromatic light through a single slit, what causes the bright fringes?
Constructive interference
What happens to the intensity of the fringes as you move away from the central fringe?
It decreases
How does the width of the obstacle affect diffraction?
Decreases diffraction
What type of pattern is formed when monochromatic light is diffracted through a single slit onto a screen?
Interference pattern of light and dark fringes
When waves meet completely out of phase in a diffraction pattern, what type of interference occurs?
Destructive interference
What occurs when the gap is smaller than the wavelength?
Most waves are reflected
How does the intensity of the fringes change as you move away from the central fringe?
It decreases
What is the main result of having an obstacle wider than the wavelength in wave diffraction?
Decreased diffraction
In a diffraction pattern, what causes the dark fringes?
Destructive interference
What would happen if a wave meets an obstacle with a size exactly equal to the wavelength?
Maximum diffraction
When monochromatic light diffracts through a single slit forming an interference pattern, why is there a bright central fringe?
Caused by constructive interference
Learn about diffraction, the spreading out of waves when passing through or around a gap. Understand how the size of the gap relative to the wavelength affects diffraction and how obstacles impact diffraction.
