Working principles of simple microscope?
A simple microscope has a series of lenses that can magnify tiny particles that the eye cannot see. It uses glass slides to encase what it is that the user wants to see. They sit on a platform while the user looks through an eyepiece at the top.
What is needed for a sound to travel?
Particles, e.g gas particles in air, because sound travels through the vibration of particles. Sound waves cannot travel in a vacuum, as there are no particles.
Why is visible light considered to be radiant energy and can travel through empty space but sound waves cannot travel through a vacuum?
Well light is an electromagnetic wave and it pushes itself through space ,but sound requires particles to travel through and if there are no particles for it to travel through you have no sound
What is true about sound in a vacuum?
Sound cannot travel through a vacuum, it needs a medium to travel through as its the vibration of particles that allows its energy to progress
Sound need particles to move does this mean it can travel in a vacuum?
No, they cannot. Sound waves are compression waves (mechanical longitudinal waves). This means they travel through mediums with the particles of the medium vibrating in the same or opposite direction of the wave, as opposed to perpendicular. Therefore, a sound wave needs particles to vibrate/oscillate for it to travel. If there are no particles, it cannot travel. A vacuum is defined by the absence of matter, meaning there are no particles. Thus, sound cannot travel in a vacuum.
Are the particles in a suspension larger than the particles of a solution but are yet to small to be easily seen?
Particles in a suspension are larger than the particles of a solution, but they are not always so small that they cannot be easily seen with the eye.
How is the microscope useful?
A microscope allows the human eye to examine tiny particles that otherwise cannot be seen.
How can colloid's be distinguished from suspension?
Particles cannot be filtered from colloids. A colloid is distinguished from a solution and a suspension by the particles because they usually have an electric charge, and they repel each other, so they do not collect into larger particles that would settle out like those in solutions, and suspensions.
What are liquid drops or solid particles spread through gas?
A gas cannot easily pass through a liquid or a solid however it can be entrapped in it . If a gas bubble is formed in a liquid it moves upward and escapes out of the liquid. Gas cannot pass through a solid barrier.
When solid is dissolved in a liquid?
When a solid is dissolved in a liquid, the liquid is said to be the solvent and the solid is to be the solute. The liquid that you get after dissolving the solid into the liquid is called the solution. When a solute dissolves, the solvent particles attract the particles of the solute away which breaks the cluster of particles apart. After dissolving enough amount that the solvent cannot dissolve more, the solution is said to be saturated. It is the state when the solution cannot dissolve anymore solute. The opposite of solution is suspension. A suspension is when the solute cannot be dissolved (that is, it is insoluble) into the solvent and stays suspended in the solvent. A suspension is translucent and the suspended particles can be easily seen. While, in a solution, the particles are soluble and complete dissolve into the solvent. A solution is transparent and the particles are too small to be seen through naked eyes.
What is a homogeneous mixture in which particles are so small that they cannot be seen without a microscope?
Solution
What factor distinguishes a suspension from a colloid?
Particles cannot be filtered in Colloids but they can in Suspensions. The main difference is the particle size.
What can you see with a microscope?
The microscope is an optical instrument used to view objects or particles that cannot be seen through our naked eyes. It is also used by medical technologists to detect certain bacteria, parasites, or other foreign elements in the specimen of an individual.

How is a suspension different from a solution?
The particles are bigger in a suspension, and the solute is not dissolved in the solvent but is dissolved in a solution suspension example- sand in water, sand is the solute and water is the solvent solution example- sugar in water, sugar is the solute and water is the solvent
What is the function of a stain in microscope work?
As the cells are transparent, the components cannot be seen clearly through a microscope. We stain the cell so that we can see the components of the cell clearly through a microscope.
