Answer:
D. diffraction
Explanation:
The Phenomenon responsible for light spreading as it passes through a narrow slit is called diffraction.
Diffraction:Mechanism by which a light beam or other wave field is dispersed as a result of passing through a narrow aperture or across an edge usually followed by interference between the generated wave forms.
The effect of diffraction is significant if the width of the narrow aperture or slit is similar to the linear dimension of the wavelength incident wave. A cloud's "silver lining" is an example of diffraction in nature.
The principle that is responsible for light spreading as it passes through a narrow slit is diffraction.
What is diffraction?
Diffraction refers to the mechanism by which a light beam or wave is dispersed or spread as a result of passing through a narrow slit.
Diffraction can occur with sound, electromagnetic radiation (light, X-rays, and gamma rays) or very sma particles such as atoms.
According to this question, light is said to spread as it passes through a narrow slit. Therefore, it can be said that the principle behind this is diffraction.
