Does a reflecting telescope uses convex lenses to focus? Which type of telescope uses a concave mirror? How is spherical aberration eliminated in a reflecting telescope? What type of telescope uses a concave mirror? How are mirrors used in the Hubble Space Telescope? How does a refracting teles...
Mirror Selfie Poses – Convex Mirror Selfie The mirrors to watch, or convex, are those that we find in the streets or in self-service stores. These mirrors have a curvature that widens the parameter of the reflection. And of course, that makes them excellent for a good selfie. If you me...
Types of portable towing mirrors include: Hot spot or convex mirrors: These small, convex mirrors have adhesive on the back that stick directly to your standard side mirrors. You can position these to reduce blind spots. Custom slip-ons: These towing mirrors are custom-made for car makes, mo...
Briefly discuss: can a convex mirror or diverging lens ever produce a real image? If not, why not; if yes, how? Thin lens Thin lens It is a type of lens with a thickness that is negligible to the radius of curvature of the lens. There are two ...
Galileo was the first to use it in astronomy. Both Lippershey's and Galileo's designs used a combination of convex and concave lenses. About 1611, Kepler improved the design to have two convex lenses, which made the image upside-down. Kepler's design is still the major design of refractor...

A double convex lens (R1=R2=10cm) having focal length equal to the focal length of a concave mirror. The radius of curvature of the concave mirror View Solution Geometric centre of a spherical mirror is called its centre of curvature. ___ View...
If you want to see something in the distance, you can use two convex lenses, placed one in front of the other. The first lens catches light rays from the distant object and makes a focused image a short distance behind the lens. This lens is called the objective, because it's nearest...
Amrayis a sketchpad for 2D raytracing experiments. Primarily it's made for acoustic raytracing (Geometrical acoustics), but you can also use it for example to see how rays of light are reflected by mirrors. Main acoustic use cases:
