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

1

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
