FAQs on Diffraction - 1 Video Lecture - Oscillations, Waves & Optics - Physics
| 1. What is diffraction? |  |
Ans. Diffraction is a phenomenon in physics where waves, such as light or sound, bend or spread out as they encounter an obstacle or pass through an opening. It occurs when waves encounter an edge or an object that is approximately the same size as the wavelength of the wave.
| 2. How does diffraction occur? | |
Ans. Diffraction occurs when waves encounter an obstacle or pass through an opening that is comparable in size to the wavelength of the wave. As the waves encounter the edge or opening, they spread out and bend, resulting in a pattern of interference and diffraction.
| 3. What is the importance of diffraction in physics? | |
Ans. Diffraction is important in physics as it helps us understand the behavior of waves when they encounter obstacles or pass through narrow openings. It allows us to study the properties of waves and how they interact with their surroundings. Diffraction also has practical applications in fields such as optics, acoustics, and radio waves.
| 4. Can diffraction occur with all types of waves? | |
Ans. Yes, diffraction can occur with all types of waves, including light, sound, and water waves. However, the extent of diffraction depends on the size of the obstacle or opening relative to the wavelength of the wave. For example, diffraction is more noticeable for longer wavelengths, such as those of sound waves, compared to shorter wavelengths, such as those of visible light.
| 5. What are some real-life examples of diffraction? | |
Ans. Diffraction can be observed in various real-life situations. Some examples include the spreading of sound waves around obstacles, the bending of light around the edges of objects, the interference patterns observed in double-slit experiments, and the diffraction of water waves as they pass through small openings in a dock or breakwater.
