What type of image is formed when object is kept at F for a convex lens?
For a convex lens the focal point is the transition point between getting a real image and a virtual image. If the object is at a greater distance then F you get a real image. If the object is closer to the lens then F you get a virtual image. If the object is located at F the light rays from the object leave the lens parallel and never form any kind of image.
Which property of light allows you to see yourself in a mirror?
That it reflects from smooth conductors with a fixed direction. For your eyes to see an image, the light comming from a certain direction should all originate from the same point on your body, such as is the case when reflected waves have a fixed direction. If they are random, then light from any point on your body, when hitting the mirror, goes into any direction and you don't see an image.
At the point of a converging lens the object cannot be seen.?
Yes, but it doesn't just float there in thin air. You need something there to make the image show up, such as smoke, tissue paper, fog, steam, ground (frosted) glass, etc. If you don't have any of those, you can take a short-focus eyepiece and look at the focal point with it. In the eyepiece, you'll see the image at the focal point. (It won't look like an image. It'll look like the object.)
Why does a bullet have less momentum fired from a short barrel vs long barrel?
At the instant the gun fires, the bullet is at rest- speed zero. As the expanding gasses from the burning gunpowder reach the bullet, they begin pushing the bullet up the barrel. It's speed is increasing- and the longer the push, the higher the speed. There IS a point of diminishing returns- where a barrel LONGER than the perfect length begins to slow the bullet- you have used all the expanding gasses, and now friction is slowing the bullet. If you had a barrel 20 ft long, the bullet would not make it all the way up the barrel, it would stop.For barrels on any realistically-usable weapon, a longer barrel will provide more momentum to the bullet than a shorter one. In addition, longer rifled barrels will also impart more spin, which will increase accuracy.
What is the symbol that represents wavelength?
The wavelength, λ, of a wave is the separation from any point on one wave to the same point on the following wave along.
A is any small character such as a picture symbol or icon that appears before an item?
bullet
How can you show your religion on the front of your profile?
By a any image symbol simple./
When an image has a point of symmetry then any line containing that point will be a line of symmetry?
False
When an image has a point of symmetry then any line containing that point will be a line of symmetry true or false?
true
A point is denoted by a dot and labeled by a capital letter?
A point is denoted by a dot but may be labelled by any symbol.
Is A point is denoted by a dot and labeled by a capital letter.?
A point is denoted by a dot but may be labelled by any symbol.
What does image scanner do?
The bar code reader is special type of image scanner. Image scanners convert any printed image into electronic form by shining light onto the image and sensing the intensity of the light’s reflection at every point.
Can a 45 bullet kill you?
Yes, any bullet of any caliber can be lethal.
How are points and their images related to the line of reflection?
The line of reflection is the perpendicular bisector of any point and its image.
Why real image don't form in plane mirror?
When diverging rays from a point source fall on the plane mirror, after reflection would once again diverge and never get a chance of converging. So any diverging rays cannot form a real image and they are considered to be coming from one point and that point is taken to be the virtual image.
What does the fire safety symbol that has a exclamation point mean?
The exclamation mark on any sign is an alarm or warning. With a fire symbol, the sign is warning of combustibles nearby.
