If a dark field condenser causes all light rays to bypass the objective where does the light come from that makes an object visible in a dark field?

Oblique rays that strike the object. Oblique rays strike the object being viewed, illuminating the object and reflect light rays up through the objective.

What is the function of a condenser in refrigerator?
The condenser cools the refridgerant. This turns it from a gas back to a liquid. Absorbing heat from the stored food causes the refridgerant to change from liquid to gas. This 'warm' gas is passed through the condenser, where the heat escapes. As the gas cools, it turns back to liquid for re-circulation. If you touch the coil at the back of a fridge - you'll see what I mean.
What causes the different colors in the spectrum?
Visible light contains all of the colors with in the spectrum. The only way we see color is the bending and refraction of the visible light sending certain wave lengths back, which our brain interprets as different colors.
Which type of wave causes you to feel warm?
Any wave can convert to heat energy if it is absorbed. The warmth you feel from the Sun, if that's what you mean, is due to visible light and infrared - both of which are electromagnetic waves.
What causes a bright-line spectrum?
when you add energy, electrons move to a higher energy level (orbit). WHen they come back down, they release energy. If that energy (wave length) is in the visible light range, we see color.
What causes friction between the two surfaces?
There are irregularities on the surfaces of any material which might not be visible to the naked eyes. This rough surfaces causes friction between any two bodies.friction is caused by gravity pulling on one object making it "stick" to the other object.yo' momma!

What causes high head pressure in an air cooled condenser?
It is due to pressure rising due to a bad condenser fan motor, bad capacitor, obstructing of airflowat the condenser, or a dirty condnser.
What causes high head pressure in a air conditioner?
5 Causes of high head pressure: 1.) Dirty condenser tubes 2.) High temp entering condenser water 3.) Low flow of condenser water 4.) Water bypassing at division plate 5.) Non-condensables in the system
What happenes to refrigeration heat in the condenser?
It's transferred to the air which passes through the condenser fins.
What causes a condenser fan to run backwards sometimes?
Usually a faulty startup capacitor.
What causes Back pressure on cooling system?
Condenser Backpressure is the difference between the Atmospheric Pressure and the Vacuum Reading of the Condenser, that is: Backpressure = Atm. Pressure - Condenser Vacuum Pressure Reading Usually, the condenser vacuum pressure is read by a manometer installed at the condenser. The atmospheric pressure is read using a barometer
Ac condenser in a Chevy Venture van?
There is a mounting problem with the factory ac condenser that causes it to crack on the left side near the middle.In order to repair the problem a new condenser and special dealer supplied "j" nut is required.An aftermarket condenser may be used.The job takes about three hours and should be performed by a qualified A/C technician.

What causes objective tinnitus?
Objective tinnitus is typically caused by tumors, turbulent blood flow through malformed vessels, or by rhythmic muscular spasms.
