What is the difference between a concave and convex lens?
Convex lenses are thicker in the middle than at the edges. They refract toward the center. Only people have convex lenses. Concave lenses are used in telescopes and glasses. Concave lenses are thinner in the middle than at the edges. When light passes through concave lenses always bend away from each other toward the edges of the lens.A convex or "positive" lens is thicker in the middle and thinner at the edges. A concave, or "negative" lens is thinner at the middle and thicker at the edges. Convex lenses project a real image behind the lens; concave lenses project a virtual image in front of the lens.
Why the surface of the mercury in a glass tube is con vex end that of water concave?
Mercury has a low adhesive force to glass, it would rather bond to itself than another surface. This tends to create a spherical surface on open mercuric faces. Balanced by gravity the hemisphere flattens and creates the slight convex shape observed.
What is lateral inversion of light?
Well if you have ever seen a mirror then you'll know that when you raise your left hand then only the hand in front of it will raise, which happens to be the other one if seen from the mirror's side. Okay, so just imagine that you are standing in front of a mirror. Raise your right hand. You'll see that if you are facing yourself in the mirror, then, from your side, the right hand will be raised. But, just imagine that you actually get inside the mirror and then stand behind it and facing it, then you see that actually the mirror 'you's' left hand is raised. This is called lateral inversion. And why it happens, well....you don't think that the mirror will actually raise the right hand as well. I mean a mirror shows your reflection and if it as well raises it's right hand, as you, then it won't be your reflection. But just another person, your twin rather, copying you. get it? I tried my best to explain it but light and reflections are very confusing. I myself have so many doubts about it.And also, I hope you do realize, that each mirror, i.e., convex, concave and plane, has its own set of properties.A simpler, correct answer: Lateral inversion occurs in a plane (flat) mirror.Compared with the object, the image is reversed along the line perpendicular to the mirror surface. Usually that means front and back are reversed."Lateral" means "sideways". It's called "lateral inversion" because the reversaloften seems to be "left-right", and not "front-back".Even though I know my image is reversed front to back when I look in a mirror, it's very hard to "see" it that way. That's psychology not physics.
What is the thematic statement in the story mirror image on Alice?
identity is not embedded into either the brain or the body, but rather is a complex melding of the two
Why parabolic mirror is used in search light?
It is a property of a parabolic mirror that rays from from one of the foci of the parabola, travelling in any direction within the parabola will get reflected along the major axis. This means that these rays will travel as parallel rays. This will give a concentrated light source rather than one that is spread out across a broad area.
Is concave a shape?
Concave is not a shape, it is the term for when two lines meet facing inwards, rather than outwards (outwards is known as convex)
What is a difference between a concave and convex lens?
A concave lens is a lens in which the ends are thicker than the middle, rather shaped like this ---> )( A convex lens is a lens in which the ends are thinner than the middle, shaped like the following ---> ()

What is a disorder when the nails grow concave rather than convex?
Aside from the shape of the free edge, what is the difference between the oval-shape nail and the round-shape nail?
Do reflecting telescopes have mirror?
Telescopes just refract. This is not completely true. If we look at the HST (Hubble Space Telescope) this is a telescope that uses reflection rather than refraction. Basically light enter the telescope and reflects of one concave mirror onto another concave mirror leading to a focal point where you can see an image. (look on google images "Hubbell's optics" and a little bit down there is a double diagram with a white background.")
What type of lens is used in the eyepiece for reflecting telescopes?
A radio telescope is a reflecting telescope, and uses a mirror rather than a lens. Since radio waves are so much longer than light waves, the 'mirror' of a radio telescope is the 'dish' reflector that focuses radio waves onto its antenna, located at the prime focus of the dish.
What is ampliftion?
Amplification, if that is what you question, is the making a observed item larger. This could occur in an electronic circuit; or it could occur using a convex lens or a concave mirror. In a rather specialized application, PCR is a chemical and physical process by which a minute portion of DNA may be amplified. [Polymerase Chain Reaction]. Though in this case, the starting material is actually replicated.
What is a shape with ten sides and not a decagon?
In 2-d, the naming of polygons is such that a 10 sided shape is a decagon. Even if it is a 5-pointed star shape, it is a decagon. A concave decagon (rather than convex) but still a decagon. In 3-d, a decahedron, possibly, with the term "sides" being used for "faces".

What lens would you use to shoot a models head outside in overcast weather?
i would rather use a convex lens
Why is a katana so efficient at cutting?
Aside from being sharp, the blade shape of a katana supports a good cut. The profile of the blade is that it is convex, and this moves material being cut out and away from the edge of the instrument. Picture the knife as a wedge, but one where the sides are not flat. Rather, they sides are "rounded out" instead of being flat or concave. This helps explain why the blade of the katana is so good at cutting.
