What is diffraction?
|
Waves bend round edges or through gaps and spread out. TRAVEL AROUND CORNERS
|
|
|
Do all waves spread out when they pass through a gap or past edge of an object?
|
Yes. The amount of diffraction depends on wavelength relative to gap.
|
|
|
What causes waves to diffract more?
|
The narrower the gap or longer the wavelength the more it spreads out.
|
|
|
What happens when waves encounter obstacles (e.g. radio waves encountering tall buildings, hills etc.)
|
Diffraction causes them to bend around obstacles. The longer the wavelength the more they diffract and bend around
