What produces visible light to illuminate the specimen?
What collects light and directs it through the stage opening (converges or focuses the rays of light to a single point)?
What regulates the amount of light available to the objective lens?
What is the ability of a microscope to differentiate two closely spaced objects as being distinct from one another?
What increases as magnification of the objective lens increases?
Use of a shorter wavelength of light increases?
What is the ability of a lens in a light microscope to gather light?
what is the numerical aperture for the oil immersion lens?
What occurs when Light rays are bent or refracted as they travel through media like glass and air?
The amount of bending of light rays is indicated by?
the refractive index (R.I.)
What is the refractive index for air?
what is the refractive index for oil?
What minimizes refraction producing a clearer image with more detail?
how do you calculate Total magnification?
Ocular x Objective
What is the product of the magnification of the ocular (10x) and the objective lens?
what is the distance from the end of the objective lens to the top of the slide when the specimen is in focus
higher magnification does what to working distance?
