Lesson 8 Flashcards
1
Q
When a wave passes around a barrier or through an opening, it will bend. This is called
A
Diffraction
2
Q
The amount of diffraction depends on
A
1.the wavelength of the wave 2. The size of the opening
3
Q
The smaller the opening the more the wave will resemble the
A
Perfect circular waves form a point
4
Q
A smaller opening will show ____ diffraction than a larger opening
A
More
5
Q
A wave with a ____ wavelength will show more diffraction than a wave with a smaller wavelength
A
Larger
6
Q
When a wave diffracts when it passes the edge of the barrier the longer the wavelength results in more diffraction which is the same as
A
Diffraction through and opening
7
Q
Does the size of the barrier has an effect on the amount of diffraction
A
Yes
