sodium vapour lamps produce much higher light output (about 90 lumens/watt) they cannot be used in lighting applications where colour-rendering property is very crucial. This is because most of the light emitted from a sodium vapour lamp is concentrated in the yellow part of the visible spectrum (around 580-590 nm) On the other hand, a mercury vapour lamp is quite suitable for lighting applications. This is because, the mercury vapour lamp can feed almost the entire visible region (380-780 nm) of the human visual system.
If monochromatic light is used instead of a sodium vapor lamp in a diffraction grating experiment, the resulting spectrum will contain a single wavelength with evenly spaced interference fringes. This is because monochromatic light consists of only one specific wavelength, resulting in a clear and distinct pattern of interference.
By the colour of the light that they emit. Sodium vapour lamps produce yellow/orange light while Mercury vapour lamps produce white light.
Similiar to a flourescent light. The ignitor provides a high voltage potential to excite the sodium gas within the bulb.
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.
When sodium iodide is exposed to light, it may undergo a photochemical reaction where it can decompose or form other products. This is because the light energy can excite the molecules in sodium iodide, leading to potential photoreactions.
In a diffraction grating experiment, the relationship between the diffraction angle and the wavelength of light is described by the equation: d(sin) m. Here, d is the spacing between the slits on the grating, is the diffraction angle, m is the order of the diffraction peak, and is the wavelength of light. This equation shows that the diffraction angle is directly related to the wavelength of light, with a smaller wavelength resulting in a larger diffraction angle.
Diffraction of light waves is the bending of light as it passes around obstacles or through small openings. It results in the spreading of light waves and the formation of interference patterns. Diffraction is a fundamental property of waves and is used in various applications such as microscopy and spectroscopy.
No, the lattice spacing of a NaCl crystal cannot be determined with sodium yellow light alone because the wavelength of light used for diffraction needs to match the spacing between planes in the crystal lattice. Since the lattice spacing of NaCl is much smaller than the wavelength of sodium yellow light, other types of radiation such as X-rays are typically used for diffraction experiments to accurately determine the lattice spacing.
Diffraction is the bending of light waves around obstacles or through small openings. The amount of diffraction that occurs is directly related to the wavelength of the light. Shorter wavelengths result in less diffraction, while longer wavelengths result in more pronounced diffraction effects.
Monochromatic light is light composed of a single wavelength. One example of monochromatic light is the laser, which emits light of a very specific color or wavelength, making it highly monochromatic.
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.
