What happens when light falls on obstacles or small apertures comparable to the wavelength of incident light?
What happens when light falls on obstacles or small apertures comparable to the wavelength of incident light?
- The light changes color
- The light bends around the corners of the obstacles or apertures (correct)
- The light stops propagating
- The light speeds up
What effect does diffraction have on the spreading of light?
What effect does diffraction have on the spreading of light?
- It causes the light to narrow down
- It changes the color of the light
- It has no effect on the spreading of light

What is Huygens's principle related to diffraction?
What is Huygens's principle related to diffraction?
- It states that light travels in a straight line
- It describes the reflection of light
- It is unrelated to diffraction
- Each point on the wave front becomes a source of secondary disturbance and sends secondary wavelets (correct)
