Focal length of spherical mirror formula
Did you know?
WebThis mirror, this time instead of concave, this is a convex mirror. So its focal length is behind the mirror. So what do we do now to figure out where the image is? We, again, use the mirror equation. We're gonna use the same equation. We're gonna have one over the focal length. And, again, I immediately have to make a decision on the sign. WebAnswer: From the image position formula: 1/o + 1/I = 1/f 1/ (100 cm) + 1/I = 1/ (30 cm) 1/I =0.023/cm I = 42.85 cm 2) A lens forms an image at 25 cm from it, where the real object …
