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.
How do you see a virtual image if the rays of light are not actually meeting?
If you look at something in front of you, light bouncing off that thing enters your eye and you say you can see the object. If now you put a mirror between you and the object, and if you move around you can find a place where you can see it "in the mirror". The object appears to be "through the mirror". The light rays have been bent through angles, but your eye is deceived to believe the object is behind the mirror. It is called a virtual image, because there is nothing to be found at the apparent place where the light appears to come from. That apparent source is called the virtual image. In lenses, the light is bent in such a way that it appears to the eye to come from a place different from the true position of the object. Also a virtual image. Incidentally, when you "see" anything, it is because your eye lens has focused light rays onto your retina. Just like a camera lens focusses onto the image plane (film or sensor chip). That focussed image is a real image. If you look at the sun, it will burn a hole in your retina, the shape of the sun.
What is meant by focus of a concave mirror?
the point at which image is formed when light rays come parallel from an object at infinity.
Where does the color of the object come from in physics?
All color is imaginary and is constructed by your brain - it's a code for the frequencies of reflected light.
Sentence for emanate?
To emanate is to come from something. An example sentence would be: They were shocked by the way the light would emanate from the object.
What is refliction?
when the ray of light enters a medium in bends a come out this is known as refliction of light
Where does light from an object come from?
the object is reflecting the light from anoher source unless it producs it
Does an opaque object reflect or absorb light?
An opaque object absorbs all the light that hits it. That's whythere's never any light left to come out of the other side.
Why is is that you can't see a non-luminous object if there is no luminous object present?
The fact that we see things is based on LIGHT. Light from an object must come to our eyes - whether the object emits light itself, or reflects it from some other light source.

What are shadow?
shadow is a black areashadow is formed when a opaque object is come in the path of lightWhen light passes through opaque object, some of it would be blocked and form a shaedow.The shadow is formed according to the shape of the object as light moves in straight line.When light source is blocked by an opaque /translucent object a black spot is formed on the opposite side of the light source ...that black spot is called shadow.CHARACTERISTICS OF SHADOWS?black in colour .?outline of structure of the object.?size depends upon the light source and the object.?always forms on the opposite side of the light source .
What center-directed continuously changes the direction of an object to make it move in a circle?
Gravity. Thank You and Come Again.

What is the Asian desert thats name means he who enters does not come back out?
Taklamakan is the Asian desert that's name means he who enters does not come back out.
How are virtual images and real images different?
A virtual image is a copy of an object formed at the location from which the light rays appear to come. Whereas a real image is a copy of an object formed at the point where the light rays actually meet.
