What else can I help you with?
Why must the slit width of a prism monochromator be varied to provide constant effective bandwidths but a nearly constant slit width provides cnstant bandwidth with a grating monochromator?
Prisms and gratings have different dispersive properties. Grating has a linear dispersion of wavelengths meaning the band on the focal plane varies linearly with the wavelength. Prisms are not linear, the shorter the wavelength the greater the dispersion. Thus, when a spectrum is being scanned, the dispersive device needs to rotates different amounts depending on whether it is prism or grating to focus light on the exit slit. If its grating, the slit width will need to be varied minimally; if it is a prism, the slit width will need larger changes as the dispersion gets greater.
What do protons and neutrons have nearly the same of?
Protons and neutrons have nearly the same mass, which is approximately 1 atomic mass unit (amu). This similarity in mass is one of the reasons they are both classified as nucleons and found in the nucleus of an atom. However, protons are positively charged, while neutrons are neutral, leading to distinct roles in atomic structure and stability.
Who struggles to maintain their body and feels anxious about their body type?
nearly everyone
How are pure substances different from mixtures?
the importance of mixture is helps you to form new substances
Which part of the atom contains all the mass?
Most of an atom's mass is concentrated in the nucleus, which is made up of protons and neutrons. While electrons contribute to the atom's overall structure, their mass is negligible compared to that of the nucleus. Thus, the nucleus is responsible for nearly all of the atom's mass.

Which ratio is nearly constant for light travelling from air into acrylic?
The ratio that is nearly constant for light traveling from air into acrylic is the refractive index. The refractive index is a measure of how much the speed of light is reduced when it travels through a medium, and it helps determine how much light is bent or refracted as it enters a new material.
