The spreading of light into the region behind an obstruction
Select one:
a. Is known as dispersion
b. Is most pronounced when the obstruction is large with respect to the wavelength of the light
c. Is made evident by interference effects
d. Is known as diffraction
Homework Answers
Option (d) diffraction, is the correct answer.
Explanation -
Diffraction is a process of light bending around an obstacle or spreading out after it moves through a small space. Also, please note that any kind of wave can experience diffraction, including sound, radio and water.
Therefore, option (d) is the correct answer.

Consider the following diffraction problem (one dimensional). Au opaque obstruction is placed in the path of an unit amplitude plane wave normally incident on the obstruction as shown in the illustration below. Geometrical or ray optics predicts a shadow region behind the obstruction, however, due to the wave nature of light and thus diffraction off the edge of the obstruction one can observe a bright spot in this shadow region. This is sometimes referred to as the Poisson Spot? as...
