The property of light, bending around obstacles and spreading of waves into the geometrical shadow of an obstacle is called _.
Correct answer: C. Diffraction
- A. Shadow
- B. Refraction
- C. Diffraction
- D. Reflection
Explanation
The property of light bending around obstacles and the spreading of waves into the geometrical shadow of an obstacle is called diffraction. Diffraction is a phenomenon that occurs when waves encounter an obstacle or a slit that is comparable in size to their wavelength. It causes the waves to spread out and bend around the edges of the obstacle, resulting in patterns of interference and diffraction. This phenomenon is observed not only in light but also in other types of waves, such as sound waves and water waves.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
