What waves are used to kill harmful bacteria?
Ultraviolet (UV) light waves are commonly used to kill harmful bacteria. UV light damages the DNA and RNA of microorganisms, preventing them from reproducing and causing them to die. UV light is often used in water treatment, air purifiers, and sterilization processes.
Compare the relative sizes of molecules plasma memberane thickness viruses bacteria organellesand cells using the appropiate SI unit?
Molecules are the smallest, typically ranging in size from 0.1 to 10 nanometers (nm). Plasma membrane thickness is about 7-8 nm. Viruses range from 20 nm to 400 nm in size. Bacteria are typically around 1-5 micrometers (µm). Organelles are larger, with sizes ranging from 0.2 to 10 µm. Cells are the largest, with sizes typically between 10 and 100 µm.
Is viruses larger than bacteria and human cells?
Viruses are generally smaller than bacteria and human cells. Viruses are usually measured in nanometers (nm), bacteria are typically larger, ranging from about 1 to 10 micrometers (µm), and human cells are even larger, ranging from about 10 to 100 micrometers.
Unit used to measure the length of a bacterium?
The unit typically used to measure the length of a bacterium is micrometers (μm). Bacteria are typically very small, ranging from about 0.5 μm to 5 μm in size. Measurements can also be made in nanometers (nm) for even smaller bacteria.
Gram positive bacteria?
In 1884 the Danish physician Chriastan Gram developed the stain known as Gram stain with which one can distinguish the two cells of bacteria which is based on the difference of their cell wall. The gram positive cell stained purple whereas gram negative stained pink or red by gram staining. This is due to because gram positive bacteria cell wall consist of single 20-80 nm thick homogenous layer of peptidoglycan(murein)lying outside the plasma membrane. In contrast the gram negative cell wall is quite complex. It has a 2-7 nm peptidoglycan layer covered by a 7-8 nm thick outer membrane.
What is the distance from Melrose NM to Raton NM?
About 254 miles.
What is the Distance from Albuquerque to White Sands NM?
About 254 miles.
A strong line in the spectrum of atomic mercury has a wavelength of 254 nm When mercury emits a photon of light at this wavelength the frequency of this light is?
To find the frequency of light emitted by mercury at a wavelength of 254 nm, you can use the formula: frequency = speed of light / wavelength. The speed of light is about 3.00 x 10^8 m/s. Convert the wavelength to meters (254 nm = 254 x 10^-9 m) and plug in the values to calculate the frequency.

How much energy does a 185 NM wave of light have?
The energy of a 185 nm wavelength light wave can be calculated using the formula E = hc/λ, where E is the energy, h is the Planck constant, c is the speed of light, and λ is the wavelength. Plugging in the values, we find that the energy of a 185 nm wave of light is approximately 6.73 × 10^-18 Joules.
What is the size of a salmonella bacteria compared with a human cell?
50 nm
Why we use 254 NM in UV detector?
A wavelength of 254 nm is commonly used in UV detectors because it effectively targets the absorption peak of many organic compounds, particularly those containing aromatic rings. This wavelength is also optimal for detecting nucleic acids and proteins, as they exhibit strong absorbance at this range. Additionally, 254 nm is a standard wavelength for disinfection applications, making it useful in various analytical and industrial settings. Overall, its effectiveness in detecting a wide range of substances makes it a preferred choice in UV detection.
