This is the general equation of lens. This formula has been obtained for formation of real image by a convex lens. But this formula is equally applicable for the formation of virtual image by a convex lens or for the concave lens. If the surrounding medium be air, then µ1= µ3= 1...
开篇解答 凹透镜(Concave Lens)是一种中央薄、边缘厚的透明光学元件,其核心功能是使平行入射的光线发生发散。这种透镜在矫正近视、光学仪器设计等领域有广泛应用。 结构与光学特性 凹透镜的物理结构决定了它的光学行为。其两面通常为曲面(多为球面),中央区域比边缘更薄(类似两...
4.Is the lens maker formula applicable for both- concave and convex lens? Convergent (convex) and divergent (concave) lenses are the two types of lenses. The lens maker formula helps to determine the focal length, the radius of curvature of the curved surface, and the refractive index of t...
Step 3: Analyze the position of the focus relative to the concave lens- The rays converge at a point 10cm to the right of the concave lens.- This point acts as a virtual object for the concave lens. Step 4: Use the lens formula for the concave lens- The lens formula is given by:...
If two lenses of focal lengths f1andf2 are kept in contact with each other, state the formula for the focal length of the combination . If P1 and P2 are the powers of these lenses, state the formula for the power of the combination. View Solution Image Formation By Concave Lens|Sign Co...

One form of astronomical telescope, which has a large primary concave mirror to collect the light and reflect it back to a smaller secondary convex mirror, is the Ritchey–Chrétien design of 1924. Both mirrors are hyperbolic in shape, completely eliminating spherical aberration. This is the ...
