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