3. 性质不同：concave和convex通常用于描述物体的形状，但它们也可以用来描述表面、图形、光线等的曲率方向。例句：- The cave has a concave surface which captures echoes.洞穴的表面呈凹形，能吸收回声。- The convex lens bends light rays to focus them.凸透镜会弯曲光线以聚焦。4. 几何性质不...
The convex lens has a focal point on both sides of the mirror. For example, when it is a thin lens, the distance between the two focal points and the center of the lens is approximately equal. The focal length of a convex lens is the dis...
For a concave lens, R1 is negative and R2 is positive. The lens maker formula for the concave lens is given by, 1f=−(μ1μ2−1)(1R1+1R2) For a convex lens, R1 is positive and R2 is negative. The lens maker formula takes the following form, ...

What is difference between concave and convex lens? Convex or converging lenses allow the light rays to converge or meet at one point once they pass through the lens. They produce different types of images. On the other hand, concave or diverging lenses spread out the light rays that pass ...

Concave-convex lenses are also called meniscus lenses. The lens has an external convex surface and an internal concave surface. If the radians outward are greater than the radians inward, the lens has a regular focal length and is used as a magnifying glass. Products Description Material: Opti...
To solve the problem step by step, we need to determine the nature of the image formed by the combination of a concave lens and a convex lens, both having the same focal length of 20 cm. Step 1: Identify the Focal Lengths - The
