What kind of microscope do you need to see particles?
To see particles, such as individual cells or microorganisms, you would typically need a light microscope. However, to see smaller particles like viruses or nanoparticles, you would need an electron microscope.
Why a microscope is necessary in order to observe brownian motion?
A microscope is necessary to observe Brownian motion because the movement of particles is very small and needs to be magnified in order to be visible to the human eye. The microscope allows us to see the random motion of the particles as they collide with each other and move in a liquid or gas. Without a microscope, the individual particle movements would be too small to detect.
How does the accelerating voltage affect the speed of charged particles in an electron microscope?
The accelerating voltage in an electron microscope directly affects the speed of charged particles. Higher accelerating voltage results in faster-moving particles, which can improve the resolution and clarity of images produced by the microscope.
In a suspension particles cannot be seen through a microscope?
In a suspension, particles are visible through a microscope because they are not dissolved but rather dispersed in a liquid or gas. The particles are larger than those in a solution, which is why they can be observed individually.
What size particles can a light microscope see?
A light microscope can typically resolve particles as small as 200 nanometers in size. This limit is known as the resolution limit of a light microscope due to the wavelength of visible light.Particles smaller than this limit may not be visible without additional techniques like fluorescence or electron microscopy.
