Answer:
b) the refracted ray has an angle of 90 degrees
Explanation:
The angle of incidence is measured with respect to the normal separation of the media. The critical angle for total internal reflection occurs is:
Here 
and 
are the refractive index of the mediums. This equation is an application of Snell's law, for the case where the refracted ray has an angle of 
.
Answer:
350x
Explanation:
In a microscope the objective has higher magnification than the eyepiece so, this is a microscope
The magnification of a microscope is given by the product of the magnifications of the eyepiece and and the objective.
Objective lens magnification = 35x =
Eyepiece magnification = 10x =
Total magnification
Total magnification is 350x
Unless you are a mutant....I don't think you would make it. I'm 5'8" and most people are 6'7" or less. It's bsically impossible to do. :)
