Unit 5, Wave Properties Flashcards
1
Q
Diffraction
A
The spreading out of waves when they meet obstacles into areas the waves wouldn’t be if they only moved in straight lines
2
Q
When wavelength is smaller than slit width, diffraction is …
A
very little
3
Q
When wavelength is equal to or greater than the slit width, diffraction is …
A
greater

A
A zero or constant phase difference
The same frequency
The same amplitudes
Oscillations in the same direction
