WebFeb 15, 2024 · A concave lens has a focal length of 20 cm. At what distance from the lens a 5 cm tall object be placed so that it forms an image at 15 cm from the lens? Calculate the size of the image formed. A convex lens of refractive index=1.5, covered at the convex surface behaves as a concave mirror of f=20cm. WebJul 4, 2024 · Focal length of concave mirror f=-15 \,cm f = −15cm magnification =2 = 2 (for virtual image) Linear magnification m=\frac {\text { size of image }} {\text { size of object … bad bunny te bote english lyrics WebWhen the object is located at the focal point of a concave mirror , the rays leaving the mirror are parallel, and no image is formed. Since Dina observed that her image disappeared when she was about 30 cm from the mirror , we know that the focal length must be f + 30 cm . Also, for spherical mirrors, R = 2 f. Thus, the radius of curvature of ... WebJul 3, 2024 · Focal length =15cm. Image distance=10cm. Object distance =? We know that: 1/v +1/u = 1/f. 1/10+1/u= 1/15. 1/u= 1/15 - 1/10. 1/u= 10-15/150. 1/u= -5/150. 1/u = -1/30.
