Type of image of convex lens?
a convex lens looks like an oval from the side. it can be used in the glasses of a long sighted person. i really should be doing my homework right now. i have been doing it since 11am and it is now 15.43pm.
What are the practical uses for concave and convex mirrors?
Some practical uses for concave and convex mirrors are in medical instruments, car mirrors, and telescopes.
Does a telescope use a convex lens?
Reflecting telescopes don't use lenses - they use mirrors (hence 'reflecting'). Light goes in the top, hits a concave mirror at the bottom of the tube which makes the light converge when it is reflected, then bounces back up to the top where it hits a smaller secondary mirror, where it is directed down the eyepiece. Do you mean refracting telescopes? If so then these do use lenses, the amount depends on the telescope. The most simple form has an objective lens which focuses the light, and then an eyepiece which has a lens in it to magnify the image. The objective lens is convex on the side pointing out of the telescope, and is flat on the other side.
The difference between lens and mirror?
In lens light passes right through the glass and reaches the other side. In the case of mirror the light hits the glass and instead of passing through to the other side of the glass it gets reflected back. This is because of the silver coating on one side of the glass.
Which type of mirror uses its outside as the reflecting surface?
convex mirror

Uses of Convex Lenses?
A convex lens is used to make objects appear larger and they are used in eyeglasses. Other uses for convex lenses include magnifying glasses, binoculars, and cameras.
What does binocular uses?
Binoculars uses lenses for magnification mainly. Two convex lens and prisms are used
What tool besides a telescope in a science lab uses two convex lens?
Microscope
What instrument uses a convex concave and a flat lens?
a camera and a fit Chinese girl
Which type of telescope uses a convex lens to increase the size of the image being viewed?
refracting
List two uses for concave lens?
Both concave and convex lenses are used in glasses; A microscope, like a reflecting telescope, uses a concave mirror, a plane mirror, and a convex lens; A refracting telescope uses two convex lenses to magnify images in the sky; binoculars use concave lenses to improve detail.
How are reflecting and retracting telescopes different?
A reflecting telescope is different from a refracting telescope because a reflecting telescope uses a concave lens, a plane mirror, and a convex lens. While a refracting telescope uses two lens.
Name two lenses used in stage lighting instruments?
There are a variety of lenses used in theaterical or stage lighting. Here is a short list and their uses: Plano-Convex- This lens is used in standard Ellipsoidal Spotlights. One side is flat(plano) and the other is Convex. Convex-convex- This lens is also used in conjunction with Plano-Convex. This, however, has both sides of the lens as convex. Fresnel lens- Used in fresnels to disperse the light Par- These lenses are intergrated into the filament, envelope, and base of the lamp. These are bubble type lenses.
How many flat or curved surfaces are on a lens?
It depends on the uses the lens are going to be put to. A lens may have a convex front and a flat back, or a convex front and a concave back, or even a convex surface on both front and back. Or even concave on both the front and back.Concave means bowed inwards.Convex means bowed outwards.
