Uses of Concave Mirror. 1. Large sized concave mirrors are used to focus solar energy on an object to be heated. Due to a limited amount of oil and gas, the importance of solar cookers can no longer be ignored. 2. Concave mirrors are used as reflectors

Why are concave mirrors used in telescopes?Reflecting Telescopes:Reflecting telescopes quickly replaced refracting telescopes for professional observatories as it became apparent that their mirror could be manufactured much larger than the lenses of refracting telescopes. This means that reflecting telescopes...
A mirror is a shiny surface that reflects the light rays falling on it. Concave, convex, and plane are the three main types of mirrors. The equation which relates the focal length with the object and image distances is cal...
is how to economically cut two-dimensional irregular shapes from a given stock sheet. An irregular polygon can have sides of any length and each interior angle can be any measure. They can be convex or concave, but a 这就是为什么很大数量的产业总更加频繁地面对是如何经济上削减二维不规[...
aThese products are recommended to be used at pipeline construction and repair in flooded soils and silted area, at crossings with different types of swamps, concave and convex curves and adjacent curvelinear sections on rotation angles on horizontal plane, sections of pipeline outlet to the ...

A vehicle is travelling along concave road then along convex road of same radius of curvatures at uniform speed. If the normal reactions on the vehicle as it crosses the lowest point of concave surface, highest point of convex surface are 1.5×104N,0.3×103N respectivel...
If an object is placed 30 cm in front of the convex lens, find the position of the final image formed by the combined system. View Solution Q2 A convex lens of focal length 10 cm placed coaxially 5 cm away from a concave lens of focal length 10 cm.if object is ...
aFrom the architectural and engineering point of view, the arch geometry of the concave shell as well as the geometry of the convex shell are changed into a new structure that generates bending movements under load (the impact of the player’s touch). 从建筑和工程学观点,凹面壳的曲拱几何以及...
