WebMEASUREMENT APPARATUS: spherometer, lenses, plane surface, meter- stick Measure the distance a between the tips of the tripod legs a several times. Measure the high h a few times on the various places on the surface of the spherometer. Measure the zero position of the spherometer on the plane surface a few times. Record all data into WebA student measure the height h of a convex mirror using spherometer. The legs of the spherometer are 4 cm apart and there are 10 divisions per cm on its linear scale and circular scale has 50 divisions. The student takes 2 as linear scale division and 40 as circular scale division. What is the radius of curvature of the convex mirror ?

WebA spherometer is a device that does just as the name suggests: it measures (ometer) a sphere (sphere). But what exactly would you measure on a sphere? You could measure its … WebThe spherometer was zeroed on the flat before each measurement. Repeatability of the zero measurement at each reading was ±0.0001" (in fact, the reading never varied by more than 0.0001"). NOTE: This does not mean that the absolute value of the depth measurements were of 0.0001" accuracy, only that readings were repeatable to this precision.
