What type of light produces clear diffraction fringe patterns?
infrared light
white light
ultraviolet light
monochromatic light
|
What happens at bright fringes in a laser diffraction pattern?
only refraction occurs
destructive interference
constructive interference
no interference
|
Why don't we typically notice light diffraction in everyday life?
openings are usually larger than light wavelengths
obstacles fully block light
white light has poor diffraction
diffraction is too weak to observe
|
What happens when white light passes through a narrow slit?
A spectrum of colours
A pattern of bright and dark fringes
the same pattern as laser light
no diffraction pattern
|
What are the light and dark lines called in a laser diffraction pattern?
shadows
spectra
fringes
wavelengths
|
What type of interference causes bright fringes in laser diffraction?
destructive
particle
constructive
wave
|
What causes waves to bend around obstacles?
reflection
refraction
absorption
diffraction
|
Why is monochromatic light best to clearly see diffraction?
it contains a single wavelength
it is laser light
it is very bright
it creates colourful patterns
|
What happens in areas of destructive interference in diffraction?
wave peaks and troughs cancel out
waves combine constructively
wave troughs align
wave peaks align
|
Diffraction occurs when waves spread out or bend as they pass through:
large gaps
openings or around obstacles
optical lenses
|
What is the name given to light consisting of a single wavelength?
|
What causes waves to spread out or bend during diffraction?
|
What type of light produces a spectrum of colors when diffracted?
|
Briefly explain why laser light produces clear diffraction fringe patterns compared to white light.
