Why isn't there fringes in diffraction of water wave but bright and dark fringes in the diffraction of light wave?
Diffraction is the phenomenon of a wave bending around an obstacle or passing through a narrow opening, resulting in a change in direction and spreading out of the wave.
Diffraction of water waves and light waves follow the same principles, but there are some key differences. Water waves have longer wavelengths and can only diffract around larger obstacles, while light waves have shorter wavelengths and can diffract around smaller obstacles. Additionally, water waves experience more diffraction in shallow water, while light waves experience more diffraction in air.
The amount of diffraction in water waves is affected by the wavelength of the wave, the size of the obstacle or opening, and the depth of the water. Longer wavelengths and larger obstacles will result in more diffraction, while shallower water will also increase the amount of diffraction.
Diffraction of water waves can cause navigational challenges for boats and ships, as the waves can bend around obstacles and create unexpected currents and turbulence. In terms of marine structures, understanding the diffraction patterns of water waves is important in the design and placement of structures such as breakwaters and offshore platforms.
Yes, diffraction of light waves can be observed in everyday life. For example, when you see a rainbow, you are witnessing diffraction of sunlight through water droplets in the air. Diffraction can also be observed when light passes through small openings, such as in the pattern created by a CD or DVD.
