How Do Smoke Particles Move in a Glass Tube Observed Under a Microscope?

AI Thread Summary
A microscope is necessary to observe smoke particles in a glass tube because they are too small to be seen with the naked eye. The smoke particles appear as spots of light due to the scattering of light by these tiny particles. Their movement is influenced by the random motion of air molecules, which collide with the smoke particles, causing them to move in various directions. Understanding these principles helps explain the behavior of particles in a fluid medium. This discussion highlights the importance of microscopy in studying small particles and their interactions.

Homework Statement



Using a microscope, smoke particles can be seen moving inside a glass tube. They appear as tiny spots of light that move in various directions. The air molecules inside the glass tube cannot be seen with the aid of the microscope.

a) State why a microscope is needed to see the smoke particles.

b) Explain why the smoke particles appear as spots of light.

c) State what makes the smoke particle moves in this way.

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
