Step 4: Drawing a Labelled Diagram of a VirusTo illustrate a virus, we can use the example of a bacteriophage, which is a virus that infects bacteria. Here is a simple labelled diagram: (Caψd)|(Head)|(Collar)|(Tail)|(BasalPlate)∣(TailFibers) Labels:- Capsid: The protein coat tha...
Draw a ray diagram for the formation of image by a compound microscope. View Solution Q3 Define the magnifying power of a compound microscope when the final image is formed at infinity. Why must both the objective and the eyepiece of a compound microscope have short focal le...
Due to the changes in refraction of light, the light rays coming from a distant object appear to be coming from the image of the object inside the ground. This is called a mirage. When the earth's surface is heated by the sun, the temperature of air inc
SERS spectra were acquired using a Jobin Yvon Raman micro spectrometer (HR800), which utilized a 632.8 nm excitation laser (He-Ne laser) and a microscope with a 50× objective lens. Raman spectra were collected once with 1 s integration time over a spectral range from 490 to 1630...
(A) Images of a nanoprobe in solution taken using brightfield (left-hand panel) and fluorescence (middle panel). The right-hand panel is a diagram of a nanoprobe including dimensions of vertex cylinders and tip. (B) Schematic diagram of the flow cell showing an upper 'holding area' for ...
where the typical temperature ranges from 298 to 310 °K. For example, a steady temperature increase of 1.9 °C is calculated46for a 1064-nm 100 mW laser in the focus of a microscope objective of 1.3 numerical aperture, in water, after only a few milliseconds. Considering the at that ...
