Question

A concave spherical mirror has a radius of curvature of magnitude 20.2 cm (a) Find the location of the image for the following object distances. (If there is no Image formed enter"NONE") object distance (cm) Image distance (cm) location in front of the mirror 20.2 in front of the mirror 10.1 in front of the mirror (b) For each case, state whether the image is real or virtual object distance (cm) real/virtual -Select 20.2 10.1 Select (c) For each case, state whether the image is upright or Inverted, object distance (cm) real/virtual ---Select 20.2 ---Select- 10.1 --Select (d) Find the magnification in each case. (If there is no Image formed enter"NONE") object distance (cm) magnification 39.2 20.2 10.1

(a)

Object distance(cm)	Image distance(cm)	Location
39.2	13.6	in front of the mirror
20.2	20.2	in front of the mirror
10.1	infinity(none)	none

(b)

Object distance(cm)	Real/virtual
39.2	real
20.2	real
10.1	real

(c)

Object distance(cm)	upright/inverted
39.2	inverted
20.2	inverted
