What does the “light” in light microscope 🔬 mean
Image is transmitted through light
What are Swan cubes
Prisms that split light into 2 since there’s two eyepieces
Open unlabeled microscope and label it page 23 of notes
Answer on notes
What is the main lens
The Objective
What is refraction
Bending of light path as it passes Different mediums
Go label a refraction of light diagram including the different angles
Answer on notes
Is light refracted away or towards the Normal and does in travel slower of faster in a less dense medium?
Away from the Normal and travels faster in a less dense medium compared to a dense medium
What is refractive index
Measure for how much the speed of light is reduced in a medium
What is Spherical aberration
Optical illusion, all light is not coming to focus at the same point
Chromatic aberration is rainbow 🌈 , What is its explanation
White light is made up of all the rainbow colors then when split up they all appear. Google to be sure
Label a principle foci diagram
Answer on notes
For which objective do we use oil immersion and why
100x objective
What is the difference between rough and fine focus knob
Rough move stage up and down in big steps and fine focus in micro steps.
What is function of stage
Holds slide in place
Function of diaphragm
Controls the amount of light entering and passing through the specimen
Two functions of the condenser
1.powers light onto the object
2.brings cones of light together
True of false, the higher the resolving power, the more clearer the picture is
True
Electron microscope shows greater detail compared to a compound light microscope
True
