How does diffraction affect waves?
Diffraction is the bending of waves around obstacles or through openings. It causes waves to spread out and change direction, affecting their intensity and pattern. This phenomenon is commonly observed in sound, light, and water waves.
How do diffraction spikes in vision affect the perception of light sources?
Diffraction spikes in vision can cause light sources to appear as if they have spikes or rays extending from them. This can distort the perception of the light source's shape and intensity, making it appear different from its actual form.
Why does diffraction occur and how does it affect the behavior of light waves?
Diffraction occurs when light waves encounter an obstacle or aperture that causes them to bend or spread out. This phenomenon happens because light waves can diffract around the edges of an obstacle, causing interference patterns to form. Diffraction affects the behavior of light waves by changing their direction and intensity, leading to phenomena such as the spreading of light beams and the formation of diffraction patterns.
How does the interference pattern change when the number of slits in a diffraction grating is increased?
When the number of slits in a diffraction grating is increased, the interference pattern produced will have more distinct maxima and minima. The fringes will be narrower and more closely spaced, leading to a more defined and detailed pattern. Additionally, the overall intensity of the diffraction pattern will decrease due to light being spread over more orders.
What are the changes in diffraction pattern if monochromatic light is replaced by white light?
If monochromatic light is replaced by white light, the diffraction pattern will show a range of colors instead of a single color. This is because white light is a mixture of different wavelengths, each diffracting at different angles. The resulting diffraction pattern will be more colorful and dispersed compared to the pattern produced by monochromatic light.

What will happen if mercury lamp is used instead of sodium lamp in plane diffraction grating exp?
Using a mercury lamp instead of a sodium lamp in a plane diffraction grating experiment might result in a different wavelength of light being emitted. This would affect the interference pattern observed on the screen, leading to a shift in the position of the fringes. Additionally, the intensity of the light and the overall visibility of the interference pattern might also be altered.

How do you apply the diffraction of light in the real life?
The diffraction of light in the real life can be seen as a rainbow pattern on a DVD or CD. The closely spaced tracks function as diffraction grating. A credit card's hologram is another example diffraction light application in real life. The grating structure on the card produces the desired diffraction pattern.
Which device could produce a diffraction pattern consisting of a central bright fringe with parallel secondary fringes that decrease in intensity with increasing distance from the center of the screen?
A double-slit device would produce a diffraction pattern with a central bright fringe and parallel secondary fringes that decrease in intensity with distance from the center of the screen. This pattern is a result of interference of light waves passing through the two slits.
Is diffraction pattern itself is due to the interference of light?
Yes.
How does interference vs diffraction affect the behavior of light waves in a double-slit experiment?
Interference in a double-slit experiment occurs when light waves overlap and either reinforce or cancel each other out, creating a pattern of light and dark fringes on a screen. Diffraction, on the other hand, causes light waves to spread out as they pass through the slits, leading to a wider pattern of interference fringes. Both interference and diffraction play a role in shaping the overall pattern of light in a double-slit experiment.
How does a diffraction grating affect white light?
A diffraction grating separates white light into its component colors by bending and spreading the light waves. This creates a spectrum of colors, similar to a rainbow.
What happens to the intensity of the bright fringes at a higher order m?
The intensity of the bright fringes at higher orders of diffraction m decreases because the light is spread over a larger area due to increased diffraction angles. This results in less light being concentrated at each individual bright fringe.
