Which of these waves will diffract the most when passing through a 20 cm wide opening in a barrier?
A)a wave with a wavelength of 25 cm
B)a wave with a wavelength of 2 cm
C)a wave with a wavelength of 0.05 cm
D)none of these waves will diffract at all

Question

Quizplus · Accepted Answer

The degree of diffraction is directly proportional to the wavelength of the wave. The larger the wavelength, the more the wave tends to diffract around obstacles. Hence, the wave with the largest wavelength, i.e., a wave with a wavelength of 25 cm will diffract the most when passing through a 20 cm wide opening in a barrier.
